Extend functionality to Moodle 4.5

[lucaboesch]

In Moodle 4.5, this plugin stops working.
This is maybe related to https://tracker.moodle.org/browse/MDL-79668 or https://tracker.moodle.org/browse/MDL-81661.

Hi @lucaboesch
Thank you for your info.

The filter does not depend on a specific version of Font Awesome.

But we've just made a new release for Moodle 4.5 with the new text_filter class. Can you check if it works for you?

Cool @voegii for that quick fix. 🚀 I'm not using it, but seeing that it is still in use is nice to see.

Greets to both of you guys
