CK5 induced scenarios - publish a new contrib module with text filter plugins

Problem/Motivation

ck5 destroys content in various scenarios:

1. Videos getting wrapped in p elements causing wet-boew to be unable to play videos
2. spans with anchors failing
3. table tfoot element being removed.

The text filter plugins we developed is how we worked around these ck5 induced scenarios.

Steps to reproduce

Upgrade from ck4 to ck5

Proposed resolution

Publish a new contrib module, since this is wider than wxt scope.

Remaining tasks

Publish a new contrib module, perhaps cook in the plugins into the baseline text filter plugin configs
