Documentation improvements

• Use master instead of the nightlies as that is more stable
• Currently the Allen CI's documentation relies on the nightlies to be able to push the documentation. It would be better to have a solution that doesn't rely on them.
• Publish the documentation for every merge request

changed title from Do not rely on nightlies for documentation jobs in Allen CI to Documentation improvements

changed the description

The documentation is published on a site using a webEOS project. Therefore, it is not straight forward to do this for every merge request / branch. We could create a second webEOS project as test site, but then have to fork the repository for testing the documentation as described here. This is necessary because the site is configured globally for the repository.

It is possible to download the artifacts and view the built site offline, seems to work for the Moore docs

I had a look at the first two points here !834 (closed)

Oops. Maybe I spoke too soon - I didn't see that the previous solution relied on the nightlies to access the HLT1 selection API.

@dovombru seems like there is an ongoing issue: https://gitlab.cern.ch/lhcb/Allen/-/jobs/22330183#L66

Is it possible to not rely on the nightlies? Perhaps can one use the compiled Allen version and use eg. ./toolchain/wrapper make -C doc html?
