docs(client-presence): changelog & changeset updates

[jason-ha]

1. Setup changeset to be used for all Presence changes
2. Update CHANGELOG to reflect 2.50 release notes and [vague] 2.4.0 history

[tylerbutler]

This will end up rendered as:

Title (#23031) (#23021)

The originating PR is always appended.

[jason-ha]

Will it be added here or on line 8 (the title)?
In prior discussion you mentioned adding PR references directly in changesets when changelog is added after. Not sure to get the right thing to happen.
