setup: rename ref storage format environment variables

With the same reasoning as for git-init(1), rename the environment
variables GIT_REFERENCE_BACKEND and GIT_DEFAULT_REF_FORMAT to
GIT_REF_STORAGE_FORMAT and GIT_DEFAULT_REF_STORAGE_FORMAT, respectively.
The old names are kept as an alias to retain compatibility.

While at it, fix indentation for `GIT_REF_STORAGE_FORMAT` docs to use
tabs instead of spaces.

Allows overriding the default ref storage format for new repositories.
