Set up a staging environment for PRs and such

[baylessj]

Hotel - also maybe as a side project, set up auto-deploy forCI build artifacts from PRs to a staging URL so the results can be verified online (:

Jonathan - I would love to see that happen, not really sure what all we have in the way of a staging domain though. My first thought was to use github pages or something similar, could we do this with the existing azure-pipelines setup though?

Hotel - my initial thought was to set up a branch on this repo for gh-pages to use and then have the pipeline commit the artifacts there under a folder keyed to the PR so you'd be able to get to the build for a PR at https://purduesigbots.github.io/pros-docs/204/ or something. i'm sure there's a way to do this in azure, but failing all else i have some sample github workflows we might be able to adapt
