feat: introduce PhpUnitAttributesFixer

[kubawerlos]

#7832 and #7833 are reverted here - it was a (naive) thinking, a better approach is NOT to migrate to attributes that are not supported in a given scope (like @large and @medum are fine on method level, but #[Large] and #[Medium] are not allowed ion method level).

Quick feedback after taking a look 😉. More when it comes out of the draft.

• the regex would be good to be deduplicated
• link to a parsing phpunit source would be good so the parsing can be checked & documented if 1:1 with native phpunit

I'd rather not, for 2 reasons:

1. it is not a single place:

• https://github.com/sebastianbergmann/phpunit/blob/11.0.3/src/Metadata/Parser/AnnotationParser.php#L63
• https://github.com/sebastianbergmann/phpunit/blob/11.0.3/src/Metadata/Parser/Annotation/DocBlock.php#L41-L45
  also, it was made differently in older PHPUnit: https://github.com/sebastianbergmann/phpunit/blob/9.6.16/src/Util/Annotation/DocBlock.php

2. let's focus on providing good tests, so they keep the fixer working properly

Awesome work @kubawerlos 👏. Personally I would drop handle from test cases' names because when you consider --testdox output it looks weird (e.g. "Fix with handle·After"). Actually I would switch to testdox entirely, but it's a separate story 😉. Anyway, only one minor comment from me, please merge on your own with or without the fix.

it would be great to have an option to add the attributes without removing the annotation (which also requires checking if the attribute is already there to avoid "fixing" it multiple times). When you need to support both PHPUnit 11 (to support the latest PHPUnit version) and PHPUnit 9.6 (to support older PHP versions), the way to go is to define both the attributes (for PHPUnit 10+) and the annotation (used by PHPUnit 9 and ignored in 10+ when the attributes are present).
