chore(doc): update examples to include name for action

Add `name` parameter to the examples so that the action presentation on github is nicer - shows the name of the action rather than the workflow filename and path. 

Resolves #11 if I understand the issue correctly, as there actually isn't an `arduino-lint.yml` file in this repo, but I think the OP was confusing this with the example snippet.
