Enable AL-Go for GitHub on GitHub Enterprise Cloud with data residency

[freddydk]

❔What, Why & How

This pull request introduces comprehensive updates to improve compatibility with GitHub Enterprise (GHE) hosts. The main focus is to ensure that all scripts and workflows dynamically use the correct GitHub server and API URLs, rather than hardcoding references to github.com and api.github.com. This enables repositories using AL-Go for GitHub to work seamlessly on both public GitHub and GHE instances. Additionally, documentation has been updated to clarify support and provide guidance for GHE users.

GitHub Enterprise compatibility and dynamic host resolution:

• All PowerShell scripts and workflow files now use the GITHUB_SERVER_URL and GITHUB_API_URL environment variables instead of hardcoded github.com and api.github.com URLs for REST API calls and repository links. This affects actions such as dependency probing, deployments, pull request validation, and workflow post-processing. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
• The workflow now explicitly verifies that the AL-Go for GitHub repository itself only runs on github.com, preventing unsupported usage on GHE for the main repo.
• The gh CLI commands set the GH_HOST environment variable to ensure API calls target the correct host on GHE. [1] [2] [3]

Documentation and user guidance:

• Added a new scenario guide, Scenarios/UsingGitHubEnterprise.md, detailing how to use AL-Go for GitHub on GHE, including setup instructions and best practices.
• The README.md is updated to reference the new GHE usage guide.
• Release notes summarize the GHE compatibility improvements and clarify the support policy.

Other improvements and fixes:

• Improved template repository download logic to construct API URLs correctly for both public GitHub and GHE, and to use authenticated or anonymous requests as appropriate. [1] [2] [3]
• Minor comments and clarifications added to template scripts regarding authentication requirements.

These changes ensure that AL-Go for GitHub works reliably in both public and enterprise GitHub environments, with clear documentation and robust host detection.

link results in 404.
i think we should also stay on first party content.

All of the AL-Go specific things will be microsoft obviously, and I will add documentation on how to do this without using my algoctl cli, but it isn't simple.

   “Submit” is the act of uploading, submitting, transmitting, or distributing code or other content to any
   Project, including but not limited to communication on electronic mailing lists, source code control
   systems, and issue tracking systems that are managed by, or on behalf of, the Project for the purpose of
   discussing and improving that Project, but excluding communication that is conspicuously marked or
   otherwise designated in writing by You as “Not a Submission.”
   “Submission” means the Code and any other copyrightable material Submitted by You, including any
   associated comments and documentation.
2. Your Submission. You must agree to the terms of this Agreement before making a Submission to any

   for whom You are acting in making Your Submission, e.g. as a contractor, vendor, or agent. If Your
   Submission is made in the course of Your work for an employer or Your employer has intellectual
   property rights in Your Submission by contract or applicable law, You must secure permission from Your
   employer to make the Submission before signing this Agreement. In that case, the term “You” in this
   Agreement will refer to You and the employer collectively. If You change employers in the future and
