ci: add workflows and cli-style

[KaiVandivier]

Adds workflows:

1. test-and-release:
   1. on pushes, runs commit linting with @dhis2/cli-style, regular code linting, unit tests, (optional e2e tests)
   2. Then runs the semantic-release action which will execute on release branches to cut a new version, then publish to the App Hub and GitHub
   3. This will also push an artifact to d2-ci
2. deploy-pr: on PRs, deploys a preview dev version on Netlify
3. lint-pr-title: makes sure it matches conventional commit format
4. comment-and-close: If someone opens up an issue on this repo, a bot will close it and direct the opener to Jira

Adds style tools:

1. ESLint for functional linting
   1. NB: Many lines were flagged under import/extensions, max-params, and no-unused-vars; I made those 'warning'-level issues in .eslintrc.js to avoid blocking the PR
2. Prettier for code style
3. Husky hooks to lint on commits: check commit format and run d2-style linters

I tried adding stylelint, but I think there's a bug with it that causes it to throw errors 🤔

I made one functional refactor to satisfy the no-async-promise-executor rule for ESlint -- @turban The diff is a bit hard to read because of the indenting changes, but it'd be good to have a look and make sure that's still working 🙂

LGTM. The promise refactor works fine.
