Use apiURL to determine whether to use the token #1615

The action includes this check to determine whether to include the token in the request:

  } else if (codeqlURL.startsWith(`${apiDetails.url}/`)) {
    logger.debug("Providing an authorization token to download CodeQL tools.");
    authorization = `token ${apiDetails.auth}`;
  }

The intention is to only include the token if we are fetching from the same instance, to avoid leaking tokens.

However, the codeqlURL in this check will refer to the API url to use to download the release. For example:

https://api.github.com/repos/myrepo/codeql-action/releases/assets/

However, the apiDetails.url refers to the instance URL, e.g. https://github.com, which means the check will always fail. We therefore need to use the apiDetails.apiURL to get the appropriate comparison.

Merge / deployment checklist

  • Confirm this change is backwards compatible with existing workflows.
  • Confirm the readme has been updated if necessary.
  • Confirm the changelog has been updated if necessary.

The codeqlURL in this check will refer to the API url to use to download
the release. For example:

https://api.github.com/repos/myrepo/codeql-action/releases/assets/<id>

However, the apiDetails.url refers to the instance URL, e.g.
https://github.com. We therefore need to use the apiDetails.apiURL to
get the appropriate comparison.

Seems reasonable, but I think we want to preserve the old behaviour.

If a user provides a tools URL explicitly like tools: https://github.com/github/codeql-action/releases/download/codeql-bundle-20230317/codeql-bundle-linux64.tar.gz, I think we'll want to authenticate this too. Therefore I think we might want to loosen this to codeqlURL.startsWith(`${apiDetails.url}/`) || codeqlURL.startsWith(`${apiDetails.apiURL}/`).
