live_kit_server: Replace jwt with jsonwebtoken (#15302)

This PR replaces `live_kit_server`'s usage of `jwt` with `jsonwebtoken`.

`jwt` hasn't been updated in 2 years and seems unmaintained.

`jsonwebtoken` has significantly more downloads and appears to be a
healthier crate overall.

Release Notes:

- N/A
