the 'linkcheck' preprocessor should not block the build

[avivace]

It often happens that PRs and commits are blocked from being built and pushed because unrelated (in other parts of the document) links now appear to be broken

[ISSOtm]

Well, they fail to build, but that doesn't prevent them from being pushed, does it?

[avivace]

@ISSOtm it blocks the build so nothing new gets published when a git commit gets pushed

[ISSOtm]

Ah, fair.

Solution: split CI into two jobs, one running mdBook without linkcheck and publishing the results; the other running linkcheck.

This will still cause a CI failure, and thus raise red flags (or a red ❌, I guess), but not prevent deployment.

This can be achieved by using environment variables to override the output config, and disable some renderers, I believe.

Okay I agree with what you proposed
