GH Actions mounts docker volumes and executes the jobs from them. For some reason it doesn't clean these volumes automatically after each run. We assume that each run happens on a clean workspace and hence there are weird consequences when this assumption is broken. One of them, for example, is failure to publish documentation to GH Pages website. To publish such a documentation, we first add the website remote to the Dotty github repo. If the remote already exists, which is the case on a dirty workspace, we get an error.

GH Actions mounts docker volumes and executes the jobs from
them. For some reason it doesn't clean these volumes
automatically after each run. We assume that each run happens
on a clean workspace and hence there are weird consequences
when this assumption is broken.
One of them, for example, is failure to publish documentation
to GH Pages website. To publish such a documentation, we first
add the website remote to the Dotty github repo. If the remote
already exists, which is the case on a dirty workspace,
we get an error.
This PR should fix the failure to publish docs: https://github.com/lampepfl/dotty/runs/518302696?check_suite_focus=true
