[Tagging] Rename an individual tag

[bradenmacdonald]

"As a global staff user (instance-level super admin), I can rename individual tags in a taxonomy."

Acceptance Criteria

1. On the Taxonomy Detail Page, users with permission to edit the taxonomy (only global staff for now) should see this "three dots" menu for each tag with "Rename" as an option:
   
2. Clicking rename will make the tag name editable in-place:
   
3. Pressing ENTER or clicking elsewhere on the page will save the new name and display a toast. Pressing ESC will cancel the rename.
   
4. Make sure the whole workflow is keyboard accessible.

Previous description of deleting tags is now on a separate ticket: #260

Developer Notes

• Screenshots above are for convenience - Figma is the most up-to-date source for mockups. The scale of UI elements seen in the screenshots above may be incorrect.

@bradenmacdonald We have added a "save" and "cancel" button to the end of the row of the tag that is being edited (the save button remains disabled until the text has been edited):

Please update point 3 in the description to something like:
"Pressing ENTER or selecting the SAVE button will save the new name and display a toast. Pressing ESC or selecting the CANCEL button will cancel the rename".

Note that "clicking elsewhere on the page" no longer cancels the rename.

---

It might be worth mentioning what happens if the name change affects the tag's position alphabetically in the list i.e. the tag remains where it is currently until the page reloads or the user selects the sort icon next to the column title.

Let me know if there's anything else you need before the "pending UX changes" label can be removed from this issue.
