PHPUnit v10 just got out. Is the support planned?

See #98, which may need an update.

Quick update: for those of you coming here and looking for an alternative that works with

• phpunit/phpunit:^8.5.26
• phpunit/phpunit:^9.6.0
• phpunit/phpunit:^10.4.0

as well as

• PHP 7.4
• PHP 8.1
• PHP 8.2
• PHP 8.3

I just released ergebnis/phpunit-slow-test-detector:2.6.0 with support for all of these.
