[FIX] web_editor, website: never indent/outdent list groups

The "comparisons" website snippet uses a list group with the class set
on a UL. In consequence, the web editor considers it as a regular list
and may try to outdent it, which is not the expected behavior with a
list group. This fix ensures that ULs with the `list-group` class cannot
be in/outdented.
