feat: add GH issue creation for failing grammars

[muenzpraeger]

• Format all commit messages with Conventional Commits

• This PR fixes Automate deployment #57

• The scripts pullGrammarsFromGitHub.ts was extended to output errors for failed grammar downloads if the arg --output-errors is set.

• The output is stored in tmp/errros.grammar.json.

• The script createGitHubIssues.sh queries the output of the error file and creates new issues.

// example error output
{
  "errors": [
    {
      "language": "abap",
      "step": "Initial fetch",
      "message": "404 Not Found",
      "success": false,
      "type": "grammar",
      "url": "https://github.com/pvl/abap.tmbundle/blob/master/Syntaxes/ABAP.tmLanguage"
    }
  ]
}

Hey, thanks for your contribution! With the recent rewrite of v1.0, we have moved the grammars out of this repository. Which should fix the original issue.
