Fix PHP 8 compatibility

[alroniks]

What does it do?

It removes unused PHPUnit with the old version, also updates dependencies to fresh versions to be compatible with PHP 8.

It also fixes the link to Git.php class that should be in the proper case to discover over class-map.

Why is it needed?

To allow installation on ENVs with PHP 8 runtime.

How to test?

You can try to build a Docker image for MODX with Gitify on the board, that based on PHP 8 RC5 FPM official image.

Two changes in the composer.json and it's PHP8 compatible? :o

[alroniks]

@Mark-H I continue testing, but it fixes installation first. If other things work well, so... that's it. :)

Sweet. :D
