chore(ci): unify CI workflows (#172)

Move build and linting jobs to a single GH workflow file.
It simplifies managing the settings for these jobs and
keeping them consistent.

Reduce permissions scope for ci workflow

Allow triggering when pushing to the 'main' branch
Run on pull requests on all branches
Build when pushing tags

Run Docker workflow on push to 'main' branch
Run Docker workflow on pull requests on all branches

Cleanups:
- rename workflow
- use consistent indentation for steps
- capitalize job name
