Turn the Install category filters into toggle chips (#4926)

* Turn the Install category filters into toggle chips

- Replace the filter buttons with toggles that show which ones are active
- Add ctrl click to select more than one category
- Keep the search box and the category filter independent of each other
- Expand matching categories while a filter is active

* Fix the filter interactions the category chips missed

- Pass the selected categories to the lazy rendering batches, the old call
  used a parameter that no longer exists and threw while typing
- Keep the category filter when switching tabs, the chips stayed checked
  while the filter itself was dropped
- Put a category back to collapsed once the filter that expanded it is gone

* Document the Install category filters

- Add a guide section for the chips, ctrl click and clearing the filter
- Note that search and the category chips apply together

* Correct the category filter guide wording

- Clearing by clicking the chip only applies when it is the only one selected
- Only categories with matches expand, and only auto expanded ones re-collapse
