Run lint on each commit

[snim2]

When you are developing in a team, it's quite handy to know whether a branch or PR passes your tests or lints before you merge it in. You can do this locally, or you can also get GitHub to automate this task. For example, this commit adds an action that runs your lint, which results in this log.

Note that you can also run Cypress tests like this but if your Cypress tests use Firebase then that adds an extra layer of complexity which you might prefer to avoid.
