* Use the right serializer for performing comparison: compactwiki only
    works if the wiki reference is set, here we need a local serializer
since we never want the wiki reference

  * Fail the data migration manager initialization if two migrations are
    found with same version.
  * Improve the check to actually check all migrations but only log
    warnings if the migration is ignored, to avoid blocking the
initialization.
  * Add a few more doc

Update dependency com.deque.html.axe-core:selenium to v4.8.1

* Add an analyzer for XWiki.PDFClass
* Add a component test

* Use $xwiki.getUserName($user) to render the link directly
* Use clean=false to avoid HTML cleaning
* Add a page test

* Add the wrapping HTML macro when displaying a value if the content is likely XWiki syntax or HTML
* Refactor tests and add new tests

Add a missing component in the live data macro components list.
