PHP 8.1 Support

[BurakBoz]

Can you upgrade ezyang/htmlpurifier version? Your package currently incompatible with php 8.1

Problem 1
    - mews/purifier[3.3.0, ..., 3.3.2] require php ^7.2 -> your php version (8.1.12) does not satisfy that requirement.
    - mews/purifier[3.3.3, ..., 3.3.6] require illuminate/config ^5.8|^6.0|^7.0|^8.0 -> found illuminate/config[v5.8.0, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev] but these were not loaded, likely because it conflicts with another require.
    - mews/purifier[3.3.7, ..., 3.3.8] require ezyang/htmlpurifier 4.13.* -> found ezyang/htmlpurifier[v4.13.0] but the package is fixed to v4.16.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
    - Root composer.json requires mews/purifier ^3.3 -> satisfiable by mews/purifier[3.3.0, ..., 3.3.8].
