Race condition with build workflow

[rossjrw]

Just encountered a situation where the build and preview workflow occurred at the same time (during the merge of a PR). They both attempted to write a commit on top of the current gh-pages commit. This resulted in the gh-pages branch moving to the commit that removed the preview for the PR, whereas the commit that deployed the build for the new commit made to the main branch was lost.

I will need to investigate running workflows synchronously.

use one of:

https://github.com/lewagon/wait-on-check-action
https://github.com/fountainhead/action-wait-for-check

make sure that the requested check is not required to have happened/be happening (not all buils will coincide with a preview and vice versa)

these plugins need a token - they recommend PAT, but standard can be used if it's within tolerance:

https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting

if advising end user to create a PAT, recommend adherence to security guidelines:

https://docs.github.com/en/actions/security-guides/security-hardening-for-github-actions#using-third-party-actions

All of the above is rubbish. Actual solution: JamesIves/github-pages-deploy-action#1054

Possibly fixed in 591779e - needs confirmation

I haven't seen this crop up in ages, so calling it fixed.
