Improvements for GitHub Enterprise

[ldaneliukas]

In GitHub Enterprise there can be two different cases that the current action does not account for:

• The committer can be empty, whilst the author is present (applies to public GitHub too)
• The rate limit can be turned off completely and attempting to retrieve will throw errors.

Changes:

• Cover all cases where login can be found - committer.login, author.login, commit.committer.name and commit.author.name.
• Continue checking for the rate-limit by default but allow turning it off.

Real API response excerpt that this is based on:

{
  "sha": "fdfbacc74635350b2d6d6d78d96a80dd017f0aaf",
  "node_id": "MDY6Q29tbWl0MjE3NjpmZGZiYWNjNzQ2MzUzNTBiMmQ2ZDZkNzhkOTZhODBkZDAxN2YwYWFm",
  "commit": {
    "author": {
      "name": "u-name",
      "email": "u.name@example.com",
      "date": "2023-09-24T16:27:01Z"
    },
    "committer": {
      "name": "u-name",
      "email": "u.name@example.com",
      "date": "2023-09-24T16:27:01Z"
    }
  },
