Create a micon + linkit (and micon + linkit + link_attributes) submodule

I've updated the merge request so that this Micon Linkit sub-module is installable on Drupal 10. I've mimicked the Micon Link module's core_version_requirement, as this is a dependency.

Do I understand correctly that this issue is not postponed as ✨ Linkit for Link field Fixed is fixed?

Thanks! Yea, the blocking issue seems to be fixed!

I currently don't have the time to have a look at this again. Is this ready to review @Watergate? Setting back to "Active" for now.

I've updated the merge request by restoring the \Drupal\micon_link\Plugin\Field\FieldWidget\MiconLinkWidgetTrait trait. In the latest release, the functionality of that trait was added directly in the \Drupal\micon_link\Plugin\Field\FieldWidget\MiconLinkWidget widget, but this was also used by the \Drupal\micon_linkit\Plugin\Field\FieldWidget\MiconLinkitWidget widget.

@Grevil, I've changed the ticket to "Needs review" (we use this functionality without problems).

@Grevil: We're now in need for a solution ourselves. We'd like to use linkit field widget instead of Link (Symbol) field widget, because Linkit provides a huge better UX (See our internal ticket).

A bonus would be, if we could also make it compatible with Link Attributes: ✨ Add support for Linkit for Link field Fixed

So eventually this may end up in two lightweight submodules. One providing integration with only Linkit (dependency) and one with Linkit and link_attributes (dependencies) that also offers attributes besides the symbol?
