Update GitHub EMU GHE.com tutorial to point to the correct app

[isaacmbrown]

I am told that the app linked from this tutorial is not correct, and customers should use the standard GitHub EMU app for both GitHub.com and GHE.com.

It is useful to keep the guide because it includes the correct URL values for enterprises on GHE.com. I've updated references to the app name and copied the instructions for the installation section from https://github.com/MicrosoftDocs/entra-docs/blob/main/docs/identity/saas-apps/github-enterprise-managed-user-tutorial.md?plain=1.

NOTE: We need these updates merged before 29 October?

@jeevansd 👋 I updated this PR with some additional changes to the provisioning guides (for SAML and OIDC).

• Added the correct tenant URL for GHE.com: it helps us to have this information in the Entra docs to avoid telling people to substitute values in the Entra guides we're linking.
• Updated the sections about the access token: the required scope recently changed to scim:enterprise. I think it's easiest just to link to the docs on GitHub Docs for creating the token, in case of any future changes.
