Adjust user tag display thresholds

[nanaya]

There needs to be some minimum votes before the tag is displayed and the maximum number of tags is currently a bit high.

The exact values for either are TBD 🤷 (or maybe just make it configurable)

Configurable is probably best. I'd say 5 votes is a good starting number.

Note that this should only be for the beatmap info display. For the tag API request the client uses, all tags should be returned (as to make voting up tags with <10 votes low overhead to the player)
