Fix: tests table height

[MarceloRobert]

Summary

Replaces static height with a max limit on individual tests table, allowing tables with less data to be shorter

Changes

• Replaces static table height with max-h
• Replaces static px with tailwind's size

How to test

• Go to a page that has the individual tests table (treeDetails/hardwareDetails tests tab, buildDetails, issueDetails) and has only a few tests.
• Check that the table doesn't have whitespace at the bottom but still allows for scrolling on other pages when it has a lot of tests.
• Compare with the original

Visual Examples

Before / After:

Test with staging environment: https://staging.dashboard.kernelci.org/issue/redhat%3Aissue_2504?iv=1774001989&o=redhat

Closes #2025

@mentonin about the tests, I don't think that adding e2e tests is the right choice here. As I see, e2e tests are made to test behavior, not layout; there's also not a specific "tests table page", we would need to test something like "build details with tests" before specifying the table.
For layout tests it would be best to have a snapshot-based testing, which Playwright (the currently used e2e test library) can provide, but I'm unsure if that would even be useful in this case since the changes are not complex at all

I am fine with that
