Updated to JDK 21, gradle 8, fixed tests

[TareqK]

Changes

This is a refactor that upgrades the mvc-common library to Jakarta EE6.0 and JDK 21, allowing use on more modern servers and libraries - the tests were also fixed to account for the expiration of tokens. The main changes were to the build and namespaces of imports - with some changes to the tests using regexes.

References

solves #111

Re-Does #138 because the company that forked it is no longer active.

Testing

• This change adds test coverage
• This change has been tested on the latest version of Java or why not

Checklist

• I have read the Auth0 general contribution guidelines
• I have read the Auth0 Code of Conduct
• All existing and new tests complete without errors

Added Context

This will break the current API as it changes all the required args to another package. Will fail CI check for API Changes - but this is expected and part of the issue.

Hi @TareqK

Apologies for the delay on this PR. I understand it's been a long wait, and I appreciate your patience and the effort you've put in both with this PR and the earlier #138.

Moving away from Java 8 and javax.servlet is a major breaking change for this library. We needed to gather usage metrics, evaluate the impact on downstream consumers, before committing to dropping Java 8 support. That decision process took longer than any of us would have liked.

We've now made the call: Java 17 will be the new baseline for this library, along with Jakarta Servlet upgrades. I've
raised PR #207 on top of your work to complete the migration to the Jakarta namespace along with Gradle 8.

Thank you again for driving this forward.
