v0.3.3 - Ensure commit.template is set

We currently ensure this by simply overriding any existing template.

This is of course sub-optimal, but the previous recommendation, to
globally set `commit.template` to a relative path would otherwise make
`git commit` crash when run in a repo without first creating that
template file, e.g. by running `git mob ...` or `git solo` in the
project directory before committing anything.

This way, we don't have to globally set `commit.template`, and git-mob
will still work.

+## A note on commit template and git-mob
+
+`git-mob` _will_ currently override any existing `commit.template` setting
+in any project where it is run. It does this in order to ensure that `git
+commit` will pick up your current mob.
+
+The future plan is to do something a bit smarter, like first detecting if the
+repo already has a `commit.template` setting, and in that case, modify the
+existing template by adding `Co-authored-by:` trailers to it, or something
+similar.
