Describe the bug

When a PR workflow is triggered by the pull_request_target event (required for sending secrets to forked repositories) the action sends the incorrect SHA + Branch details to Code Climate, which results in the coverage being posted on the target branch PR. It seems like the issue is here:

The line needs to be extended to include pull_request_trigger:

  if (
    process.env.GITHUB_EVENT_NAME &&
    ['pull_request', 'pull_request_target'].includes(
      process.env.GITHUB_EVENT_NAME
    )
  ) {
    env.GIT_BRANCH = process.env.GITHUB_HEAD_REF || env.GIT_BRANCH; // Report correct branch for PRs (See https://github.com/paambaati/codeclimate-action/issues/86)
    env.GIT_COMMIT_SHA = context.payload.pull_request?.['head']?.['sha']; // Report correct SHA for the head branch (See https://github.com/paambaati/codeclimate-action/issues/140)
  }

Version of codeclimate-action you're using
v3.1.1
