fix: Use correct baseUrl when running in non-public Github instances

[mungodewar]

Issue?

When running the action against a non-public GH instance, the api request to determine build-id from Github would fail.

Bad Credentials

I believe this is due to the incorrect (public) GH instance being contacted.

How?

The fix uses:

• the baseUrl constuctor option of Octokit: https://github.com/octokit/octokit.js/blob/main/README.md#constructor-options
• the available GITHUB_API_URL environment variable: https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/store-information-in-variables#default-environment-variables

Thanks for describing your issue and suggesting a resolution!

When you refer to "non-public GitHub instances", do you mean a self-hosted runner in a GitHub Enterprise Server or perhaps GitHub Enterprise Cloud? I assume that you don't mean just a private repository using a GitHub-hosted runner.

The code you propose to change was added by the Cypress Cloud team, so I would expect that they should be involved in any changes here.
