Fixes 329

fixes #329

The approach here is to force the URL used to always be api.github.com, allowing for the users to define a different one if they want to have the carvel repositories in their own instance.

The more important thing to have into account is that the github token used has to be valid in the github instance you are retrieving the releases of the carvel tools from.

Ex: In the following case the github token used HAS to be valid in github.com

steps:
- uses: carvel-dev/setup-action@v3
  with:
    token: TOKEN-FROM-GITHUB.COM
- run: |
    ytt version
    kbld version

Ex: In the following case the github token used HAS to be valid in acme.github.com

steps:
- uses: carvel-dev/setup-action@v3
  with:
    endpoint: https://acme.github.com/api/v3
    token: TOKEN-FROM-GITHUB.COM
- run: |
    ytt version
    kbld version

Pull request overview

This PR addresses issue #329 (“Issues running in Enterprise GitHub”) by making the GitHub API base URL configurable (defaulting to https://api.github.com) so the action can fetch Carvel releases from GitHub.com even when running on GHES, while still allowing users to target a GHES API when hosting the repos there.

Changes:

• Add a new endpoint input and use it as the Octokit baseUrl when creating the GitHub client.
• Upgrade @actions/core / @actions/github dependencies and adjust Jest configuration/mocks accordingly.
• Update docs/examples (including bumping usage examples to @v3).

@jbrunton We have an issue with github@6.0.1 that is +- a year old, but not sure if upgrading to the latest version of the library is going to impact any other code on the libraries that you built underneath, so I kept it around 6.*
