chore: add generated file cache to CI

[danielbate]

Resolves this CI error.

docs is not hitting the cache as one of the cache inputs is generated on build. We should therefore also cache generated files to ensure cache validity is correctly checked.

Cache executed here.

Suggest passing through the cache-path as input arguments.

@petertonysmith94 please can you provide an example? And what's the benefit of this?

[petertonysmith94]

Hey @danielbate,
I suppose for me only having to update 2 places, rather than 4 is worth it.

This is a untested test commit, was only a suggestion :)
