✨ Add date range and comment filter to queryModerationEvents endpoint

[foysalit]

This PR adds a few more handy params/filters to the queryModerationEvents lexicon in order to allow mods to look at events

1. within a certain date-time range
2. with a certain comment/note keyword
3. with comments only
4. emitted by a specific user/mod
5. with one or more report types
6. with one or more labels added/removed

@foysalit would you mind adding a changeset for the change to @atproto/api? Adding a changeset will facilitate the next release of the api package. The command is pnpm changeset. We'll want to mark the @atproto/api package for a patch release. It will generate a file, which just needs to be checked-in to this PR. Feel free to reach out if you want a hand with it, I realize you may not have had to add a changeset here before!
