feat(hub-common): add attendees settings pane

[juliannaeapicella]

1. Description:

2. Instructions for testing:

3. Closes Issues: #8474

4. Updated meaningful TSDoc to methods including Parameters and Returns, see Documentation Guide

5. used semantic commit messages

6. PR title follows semantic commit format (CRITICAL if the title is not in a semantic format, the release automation will not run!)

7. updated peerDependencies as needed. CRITICAL our automated release system can not be counted on to update peerDependencies so we must do it manually in our PRs when needed. See the updating peerDependencies section of the release instructions for more details.

In addition to the inline feedback I've left, there's a few more changes you'll need to make on this branch to get it working when you pull this into opendata-ui and start hooking a gallery picker up w/ facets.

1. You'll need to add a method that returns the events 3 API "definition". I've done this on my branch already, you should be able to copy/paste to your branch for now. See getEventsApiDefinition.ts on PR-1476
2. You'll need to add a method to determine if the events API should be used for the current call to hubSearch. I've done this on my branch already, you should be able to copy/paste to your branch for now. See shouldUseEventsApi.ts on PR-1476
3. We need to refactor getApi.ts to use the new methods from 1 & 2 above. I've done this on my branch already, you should be able to copy/paste to your branch for now. See getApi.ts on PR-1476
4. We need to refactor hubSearch.ts so that it calls through to your new method. I've done similar for searching for events on my branch. See changes in hubSearch.ts on PR-1476

As mentioned on opendata-ui PR-13493, there's some quick changes we need to make on this PR to support the front-end behavior:

1. Extend SortOption to include firstName & lastName
2. Add a deleteHubEventRegistration method likely in packages/common/src/events/edit.ts that's publicly exported and calls through to the deleteRegistration method in packages/common/src/events/api/registrations.ts. This is needed because the contents of packages/common/src/events/api/registrations.ts are not currently publicly exported due to naming collisions with some of the interfaces.

This looks good to me, I believe we have everything we need for the attendees pane.
