rtmp-services: Add HomeGround TV

[sravsimh]

Description

I have added a new service in services.json for my Homeground TV user to be able to push directly through OBS without using cutom URL

Motivation and Context

1. My users always need to add stream url in the stream section, now by adding this service they only need to enter stream key
2. In case of changes i had trouble to communicate with all the users to change the url, using this i can change in OBS and it will reflect automatically

How Has This Been Tested?

1. I have tested it locally on my macbook and windows laptop both with intel i7 16gb ram

Types of changes

• New feature (non-breaking change which adds functionality)

Checklist:

• My code has been run through clang-format.
• I have read the contributing document.
• 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.

This is missing actually adding the service that #12841 had.

You also don't need to close and reopen PRs for every change to your branch. Just amend/rebase your branch to include whatever additional changes you want to make and push your changes (with --force if necessary) to your fork's branch. The PR will update accordingly, as it always tracks the current HEAD of your PR branch.
