This publishes translations (currently only the Danish translation) to
subdirectories named after the ISO 639-1 language code: “da/” for
Danish, “ko/” for Korean, etc.
The list of translation is an explicit list to make it easy for us to
enable/disable translations without being tied to the files in po/.
This allows us to experiment with a translation without publishing it
immediately.
I propose that we eventually move the English pages to an “en/”
directory for symmetry with the other locales. However, for now, the
pages remain at the room of our site (which works fine since we don’t
have a subdirectory named “en/” in the course).
* Extract common build steps to composite actions
This allows us to repeat ourselves less across the different jobs.
I also tested using a “reusable workflow” to factor out the common
steps. However, this starts a separate job without a shared
filesystem, which in turn requires us to upload/download artifacts
when we want to use them in several jobs. The artifacts are downloaded
one-by-one and this adds delays and extra steps to all jobs.
* Move Rust cache setup to its own build step
This made it easy to consistently setup the caching of our nested
projects via the “workspacs” config key.
This removes a bunch of boiler-plate comments which were left from the
template I used originally.
It also simplifies the name to just “Publish” since I feel this fits
better for what we do here.
