fix(replay/feedback): use dataset specific tags for search typeaheads

[aliu39]

Fixes https://github.com/getsentry/sentry/issues/75745 Previously we were using the legacy global TagStore, which includes every tag in the org and loads slower. With this hook we can fetch just the tags we need, from the right dataset

Before:

I haven't made use of the isLoading or isError states since I couldn't find such states for the search bar. Like before, the tags will appear in the list once loaded, no transition (hopefully these will be faster).
