PHP 8.3 compatibility

[rolf-yoast]

Describe the bug

The plugin is using the ezyang/htmlpurifier library via composer. This library uses the get_magic_quotes_gpc function in https://github.com/ezyang/htmlpurifier/blob/master/library/HTMLPurifier/Config.php.

1. But this function has been removed in PHP 8.0

Steps to Reproduce

1. Go to https://github.com/ezyang/htmlpurifier/blob/master/library/HTMLPurifier/Config.php
2. Search for get_magic_quotes_gpc and you can find it multiple times in the code
3. Check https://www.php.net/manual/en/function.get-magic-quotes-gpc.php

@jeffpaul the new versions of the svg-sanitizer library dropped the use of the ezyang/htmlpurifier library. Updating enshrined/svg-sanitize to the latest version will solve this issue.

@sksaju I see you've made a PR for this, thanks for that. But when will this be released? Any estimate on the ETA?

[jeffpaul]

@rolf-yoast there's some code review feedback on the linked PR that need to be resolved first, then we otherwise do a monthly check across our FOSS plugins to see which have something releasable. So unlikely that we see this get released until later in September at the earliest.
