phploc/phploc dependency in require blocks upgrade to PHPUnit 10+

[kukulich]

Describe the bug

We use dev-main version of Phing. I would like to upgrade our PHPUnit to version 10+ but I get this:

    - phploc/phploc[7.0.0, ..., 7.0.1] require php ^7.3 -> your php version (8.1.99; overridden via config.platform, actual: 8.2.4) does not satisfy that requirement.
    - sebastian/version 3.0.0 require php ^7.3 -> your php version (8.1.99; overridden via config.platform, actual: 8.2.4) does not satisfy that requirement.
    - Root composer.json requires phing/phing dev-main#dbf8041 -> satisfiable by phing/phing[dev-main].

I think phploc/phploc dependency should not be part of require. I think it should be in suggest section of composer.json

Steps To Reproduce
Try to install Phing and PHPUnit 10+.

Expected behavior

I would like to use Phing and PHPUnit 10+ together :)

This used to be a dev dependency (along with a bunch of others, but the work for #1693 moved that back to require.

Yes, phploc is now fixed however it looks there's another problem with PHPUnit 10 :(

phpunit/phpunit 10.0.19 requires sebastian/version ^4.0 -> satisfiable by sebastian/version[4.0.0, 4.0.1, 4.0.x-dev].

Should be fixed now. Mind you, the PhpUnit task might not support PHPUnit 10 yet (especially if there are breaking changes).
