chore: add prettier config, format file, add lint workflow

The prettier config was adapted from the official GitHub Actions repo,
bent to fit the prevailing style (where possible) already in the project

The intent is not to be controversial or argue about whitespace, it is just
to have a consistent easy-to-verify style specifically to avoid all arguments
about whitespace. If anything in here is objectionable, just name the setting
to alter and I can edit / re-format / re-push
