adds accordions to collapse long lists of tags on Tag Landing pages
Tag lists on the landing pages can be very long and unwieldy. To navigate and find what you're looking for more easily, the sections for Synonyms, Metatags, and Subtags can be collapsed. You can also collapse any subtag trees, or hide all tags with fandom disambigs.
The groups and all their tags are still shown by default. Click the triangle next to a section to hide or show its tags.
The buttons in the Subtags heading lets you:
"Hide all disambigged": The script does not check whether tags are attached to No Fandom or something else, because that would create a lot of background page loads and either takes forever or would have you rate-limited quickly. Instead it only recognizes a disambig, and will hide such tags. It doesn't catch all fandom-related tags, but can still shorten the list. It might also catch disambigged concepts in NF, such as "Cotton Candy (Food)" or "Berlin (City)".
The initial version of the script automatically collapsed groups and subtag trees. This logic has been removed; there's no configuration. Hopefully the ability to collapse all trees at once is more useful.
