Update PHPunit to 13.0.5

[jcsilkey]

What was changed

• Updated PHPUnit to 13.0.5
• Changed base TestCase to extend new PHPUnit\Framework\TestCase::invokeTestMethod instead of PHPUnit\Framework\TestCase::runTest
• Updated PHPUnit configuration to match current schema
• Ignore the PHPUnit result cache in git
• Tell composer to not generate a lock file

Why?

Many current versions of great testing tools/libraries (such as Pest) will not work with the current spiral/testing package due to it being pinned to an old version of PHPUnit.

Checklist

• Closes Support phpUnit 13 #81
• Tested
  • Tested manually
  • Unit tests added

@roxblnfk I've tested updating https://github.com/spiral/framework to use this branch, and the tests fail miserably. I've been holding back because I've been trying to determine if the test failures are due to breaking changes going from phpunit 10 > 13 or because of an issue with these changes.

If you simply update PHPUnit to the latest version, user tests will break.
So, I think we can just release it in v3.0.0

This way, developers will manually update the testing package to v3 and use rector to update the tests. Meanwhile, nothing will break within version 2.
