Set up Lint and Test for push/PR to master

@virtuoushub added this simple github action to lint on push/pr to master. Please suggest improvements/changes. This is the first time I have set up github actions, so any suggestions are welcome. I disabled testing for now.

👀 watching the cache step in Setup Node step - currently it reports yarn cache is not found. this feels like an issue with the workflow itself. If it happens on the next run, then i'll tinker with it some more.

lgtm overall - biggest nitpick I have is we might want to consider having the node and yarn version defined somewhere other than the GitHub action yml file and somehow configured to be read in that yml file, so there is a single source of truth for it (e.g. .nvm, package.json, etc.)

this is more of a nice to have however
