Replace Hound CI with gh action

[ribose-jeffreylau]

Hound seems unmaintained.

Its linters are outdated: http://help.houndci.com/en/articles/2461415-supported-linters

There is a suggestion in one of the issues to use reclaim-the-stack/rubocop-action.

Updating should prevent scenarios like this, where Hound was unable to recognize newer linting rules: relaton/relaton#131 (review)

@ribose-jeffreylau so what's the "action" here? Remove Hound?

[ribose-jeffreylau]

A possible next step is to do a pilot of reclaim-the-stack/rubocop-action on one of the repositories and see if it can replace Hound without errors about unrecognized cops.

.github/workflows/rubocop.yml:

name: Rubocop

on: pull_request

permissions:
  contents: read
  pull-requests: write

jobs:
  rubocop:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 1
      - uses: ruby/setup-ruby@v1
        with:
          ruby-version: 3.1
      - uses: reclaim-the-stack/[email protected]

If it can, then we can replicate the Rubocop GH action YAML (using cimas) across all relevant repos. Then, finally, disable Hound in the Hound site or remove the Hound app from all GitHub organization's GitHub Apps page.

I can start with metanorma-cli and metanorma first.
