CI: autobump workflow never finishes

[fgvieira]

The autobump workflow usually does not go all the way to the end, mainly because of "bad credentials" (e.g. autobump#63, autobump#62, autobump#59) but sometimes due to lack of disk space (autobump#64, autobump#69).

Not sure how to fix the former, but for the latter would it be possible for the snakedeploy-github-action to clean-up after each conda-env update?
Alternatively, some have suggested that deleting the /opt/hostedtoolcache folder can free up to 10Gb.

Seems to have been fixed.
