Update composer json

Hi,

in this PR I've added a scripts section to the composer.json for convenience and also a link to the list of contributors as authors.

Bonus: bumped PHPUnit to v10.5 (ugh, the lock file)

I've added the missing PHPCS scripts.

Heads-up: PHPCBF "conveniently" changes all line endings from CRLF to LF on Windows (not helpful).

@codemasher, thanks for this contribution but I decided not to merge it as it introduces more points for me to maintain.
