This commit adds a suggested hashtag section to the universe view tab. The method for suggesting hashtags is currently simple:
1. It contains a list of many possible hashtags that we could recommend
2. It calculates how many users have been talking about it in the events fetched by the Universe tab
3. It selects the Top-N most mentioned suggested hashtags in the Universe tab
This has the following properties:
1. It has some spam resistance as it ranks by unique users mentioning the tag (instead of events)
2. It is a simple way to curate good hashtags
3. It shows the ones with the most amount of people talking about it among the notes fecthed in the Universe view

Device: iPhone 14 Pro simulator
iOS: 17.0
Damus: This commit
Coverage:
1. Suggested hashtags are displayed
2. Layout looks similar to Figma
3. User count goes up (does not stay at zero)
4. Clicking on a suggested hashtag takes you to that hashtag view
5. Only the top 5 hashtags are displayed
Notes: The counts seem low, probably because there are not enough notes loaded in Universe View
Changelog-Added: Add suggested hashtags to universe view
