Deploy preview is broken

[kellnerd]

A few things which I noticed during and after merging #799

• Codecov/project check is broken: I haven't changed anything of relevance and it claims coverage changed, looking closer it's probably failing coverage report uploads.
• Deploy preview refuses to do its job (Error: Bad credentials)
• The latest ECAU release didn't inject an updated USERSCRIPT_FEATURE_HISTORY object, causing the script to advertise the previous "update Image Max URL to maximise Spotify covers" as the last change.

I am no longer seeing two of the three issues today (#810), only the deploy preview is still broken.
Since I don't have access to repository secrets, I can't have a look at the credentials, nor fix them.

I've regenerated and updated the token (it expired some time last October), so that should fix the remaining issue. 🤞

The Codecov issue might just have been a temporary issue. Regarding the last issue: The feature history only gets edited for feat PRs, not fix PRs, to avoid excessive notifications.

Also, massive thanks for helping out with the issues and PRs over the past few days! I'm hoping that I'll be able to find some time in the near future to pick up on some things in this repository again but it's been quite a struggle to find time to work on this 😞
