The example of the input `repositories` is wrong.

The example is wrong.

github-app-token/README.md

Lines 42 to 44 in 3eb77c7

	# Optional.
	# repositories: >-
	# ["actions/toolkit", "github/docs"]

repositories must be a list of repository names, not repository full names.

Please see the example of the official API document.

https://docs.github.com/en/rest/apps/apps?apiVersion=2022-11-28#create-an-installation-access-token-for-an-app

curl -L \
  -X POST \
  -H "Accept: application/vnd.github+json" \
  -H "Authorization: Bearer <YOUR-TOKEN>" \
  -H "X-GitHub-Api-Version: 2022-11-28" \
  https://api.github.com/app/installations/1/access_tokens \
  -d '{"repository":"Hello-World","permissions":{"issues":"write","contents":"read"}}'

If we pass repository full names, this action can't issue tokens.

  [cause]: RequestError [HttpError]: There is at least one repository that does not exist or is not accessible to the parent installation.
