Bug fixes

D9 compatibility

Add Views handler for entities

Also changes API: hook_embederator_embed_alter becomes hook_embederator_markup_alter

Fixes:

• Field group - patch html5 validation with tabs
• Product attributes escapes characters
• On front page, make HTML head pager links point to front page directly instead of node URL/alias
• 'Last' link in HTML head always renders 1 page more than there is

New:

• switch language names to abbreviations if the theme that is used supports it as a theme setting

Add a dependency for lity core in the lity popup module

Base theme

• Removed role="navigation" from pager.html.twig. It's invalid and core bug.
• Removed role="article" from node.html.twig. It's invalid and core bug.
