[yt-topicus]

Is your feature request related to a problem? Please describe.

Problem 1
    - neilime/php-css-lint is locked to version v4.1.0 and an update of this package was not requested.
    - neilime/php-css-lint v4.1.0 requires php ~8.1.0 || ~8.2.0 || ~8.3.0 -> your php version (8.4.4) does not satisfy that requirement.

Describe the solution you'd like
Add support for PHP 8.4

Describe alternatives you've considered
Forking

Additional context
Possibly change constraint to ^8.1 instead
