Add git-lfs to installed packages in Dockerfile

[mikaellindemann]

Summary of changes

I use Git LFS to track large files that seldomly change.
Git LFS adds some hooks to call into the git-lfs command.
However, this command is not installed in the Docker image produced by the action, so the entire action fails.

Alternative workarounds

Adding the following step before github-tag-action can be used to circumvent the missing dependency:

- name: Delete .git/hooks/*
  run: rm -rf .git/hooks/*

Breaking Changes

Do any of the included changes break current behaviour or configuration?

I believe not, since git-lfs is only invoked if its hooks are enabled.

Also, the forked action was run in a private repository, where Git LFS is configured. See log extracts below.

Would you kindly take a look at this ? It is a small change that would help out a bunch of people who are using Git LFS. Thanks !
