Make tag fetching when preparing providers optional.

Tag fetching is only needed to make sure we do not generate
packages that have already been generated. However this is just
an optimisation for CI runs. There is no harm if the tags are
not refreshed and we generate the package again locally.

Tag fetching might faile in various cases - for example when
you are in corporate environment and require specific certificates
to be available or when you are working from a worktree.

After this change fetching tag will produce warning when there is
an error and instruction on how you can fetch tags manually.
