Subject: [PATCH 03/17] Roll back node & yarn updates (#1518)

There's an issue with the way that yarn is packaged that caused #1516 due to behavior introduced in #1503. This commit reverts to the old node/yarn versions until we can fix the underlying bug.

Subject: [PATCH 04/17] Fix tests not executing (#1517)

* Emit log order

Issue #1505 spells out a problem where it appears ci-queue does not fail even when the test suite is broken. I'm unsure why this happens. To debug I'm emitting the tests that run so I can audit to make sure `rspec ./spec/helpers/yarn_installer_spec.rb:6` is executed.

If it's not, then I need to diagnose why. If it is, then perhaps there some ordering bug that's affecting the outcome.

* Update CI-queue

* Update redis version

* Use branch of ci-queue

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix failure installing yarn 1.22.22

In #1516 there were reported build failures:

```

remote: 	from /tmp/tmp.l8hWafbPfJ/lib/ruby/3.1.0/tmpdir.rb:96:in `mktmpdir'
```

This is because older versions of the yarn package have a top level directory that looks like this:

```
yarn-v1.22.19/
```

But yarn 1.22.22 has a directory named "package" instead:

```
package/
```

To work around this naming issue we can use `--strip 1` tar flag to remove the top level directory. From gnutar manfiles https://www.gnu.org/software/tar/manual/tar.html:

```
‘--strip-components=number’
Strip given number of leading components from file names before extraction.

For example, suppose you have archived whole ‘/usr’ hierarchy to a tar archive named ‘usr.tar’. Among other files, this archive contains ‘usr/include/stdlib.h’, which you wish to extract to the current working directory. To do so, you type:

$ tar -xf usr.tar --strip=2 usr/include/stdlib.h
The option ‘--strip=2’ instructs tar to strip the two leading components (‘usr/’ and ‘include/’) off the file name.

If you add the ‘--verbose’ (‘-v’) option to the invocation above, you will note that the verbose listing still contains the full file name, with the two removed components still in place. This can be inconvenient, so tar provides a special option for altering this behavior:
```

* Default to strip 0 instead of true

From the feedback:

> Minor - maybe the default for strip_components should be 0 instead of false? From this signature, I would expect that if I want it to strip components I would pass true instead of false but that would produce an invalid command.

Subject: [PATCH 09/17] Fix build timeouts with node/yarn by setting
 UV_USE_IO_URING=0 by default (#1523)

* Set UV_USE_IO_URING=0 by default

Default `UV_USE_IO_URING=0` due to build timeouts This mirrors a change by the nodejs buildpack: https://github.com/heroku/heroku-buildpack-nodejs/pull/1347

The Ruby buildpack needs this because we can install node/yarn without the `heroku/nodejs` buildpack, however this behavior triggers a warning and is generally advised against.

* Only set UV_USE_IO_URING=0 at build (not runtime)

* Make UV_USE_IO_URING=0 available for other buildpacks

* Update test to not be on deprecated stack

* Update gem versions

* Inspect ruby version instead of jar file

From https://github.com/heroku/heroku-buildpack-java/blob/b3c51f94de6a43bc656b777bc84ef2a9451371aa/test/spec/java_spec.rb#L78

> OpenJDK versions > 9 do not have the jre/lib/ext directory where we drop the pgconfig.jar

This test was added by Joe in https://github.com/heroku/heroku-buildpack-ruby/commit/248b30a420766fa3ec2e0b29581571e6089f7aee later I moved to not having a separate track for installing JVM https://github.com/heroku/heroku-buildpack-ruby/commit/648a14986020ae6c681dbbba0895fe6bb542d5fd so I removed the logic for installing a pgconfig.jar and relied on the buildpack. According to the JVM buildpack it's no longer in this updated version.

It seems the original PR was using this to test that installation logic. While we no longer need to do that (as the logic is part of the `heroku/jvm` buildpack) I wanted to preserve calling a `heroku run` to assert something about the dyno that would indicate that jruby was installed as we expect.
