The docs:tarball job is deemed to be cheap enough to run all the time
and it catches omissions in dist targets of Makefiles.
MR !5254 was missing changes to dist target in Makefile and broke docs
build from tarball without us noticing during pipeline run on the MR,
and it manifested itself only on scheduled pipelines which include
docs:tarball job.
