[Tagging] Refined Taxonomy Detail Page

[bradenmacdonald]

"As a user viewing a taxonomy in Studio, I want a simpler, more efficient experience."

Design: "Taxonomy Detail Page" in Figma "Content Tagging MVP"

Criteria:

1. The table header has been removed (so "Showing 7 of 7" no longer appears).
2. The table displays up to 100 parent tags at a time. Pagination is only required if there are more than 100 parent tags.
3. The "expand all" link and the up/down arrows have been moved to the far right of the table.
4. The counts have been updated to include the total number of grandchild tags, not just the number of direct children. This will be implemented in [Tagging] Inclusive Counts on Taxonomy Detail Page #191.

Note: if any of these changes require major changes to the Paragon DataTable, you can discuss them with @ali-hugo before spending a ton of time on it. This is still an MVP and major changes will be made in a future epic when we implement taxonomy editing.
