rtmp-services: Update Switchboard Live servers

[sarwin-github]

Description

The Switchboard Live Server URLs have been recently updated in the application, so the URLs need to be updated in OBS to match.

Motivation and Context

There were recent changes to the ingestion servers at Switchboard Live. We also removed Legacy url.

How Has This Been Tested?

• This was tested using the latest build of OBS on Windows.
• Testing consisted of going live with every server to ensure connectivity was stable.

Types of changes

• Tweak (non-breaking change to improve existing functionality).
• Removed Alt names

Checklist:

• My code is not on the master branch.
• The code has been tested.
• All commit messages are properly formatted and commits squashed where appropriate.
• I have included updates to all appropriate documentation.

The commit history is getting ugly, try to only have one commit containing the change, without any merge commits. This is why it's recommended to not use the master branch for PRs.

Commits still need to be squashed before this can be merged.

I've fixed the issues with this PR manually because the legacy ingest is gone and is causing CI failures when we try to run our services tests.

In the future:

1. Do not submit a PR from your fork's master branch.
2. Do not use merge commits to keep your branch up to date. Use git rebase instead.
3. Do not change or remove existing entries in the alt_names key. You can only add new entries. This is used so that existing user setups with the old names do not break.

If you do not follow this advice, your future PRs may be closed.
