rework theme_filter_tips to use the new Attributes, and call theme('item_list) while we're at it

Thank you for creating this issue to improve Drupal.

We are working to decide if this task is still relevant to a currently supported version of Drupal. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or is no longer relevant. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!

The current parent meta issue assigned in comment #28 seems irrelevant at this point, since the filter-tips.html.twig that ships with Drupal 11 has appropriate use of Attributes and provides no default classes anymore.

#25 📌 rework theme_filter_tips to use the new Attributes, and call theme('item_list) while we're at it Postponed: needs info :

we want to remove as many theme functions templates as possible that just duplicate things like e.g. a list and use suggestions instead.

This may be a valid point and relevant to this issue, but this seems extremely low-priority. The community has embraced Twig templates everywhere. Having this template isn't causing anyone issues. And is arguably more flexible allowing themers to completley swap out the simple nested list for a <table>, or a <details> or another component for improved readability of long filter tips.

I suggest closing this, but defer to more active core contributors for consensus.
