CICD: Build: Use Cargo.toml version instead of tag

This enables us to later always build Debian packages. If you try to use
a git sha as Debian package version you will get an error:

    dpkg-deb: error: parsing file '_staging/dpkg/DEBIAN/control' near line 2 package 'bat':
     error in 'Version' field string 'd2963ce4': version number does not start with digit

so we need to use a version that is always available.

We duplicate the bat version in another place here which is a bit bad,
but it is already duplicated a lot, so we don't make things
significantly worse. It is still kind of nice to not have to figure out
a good and robust way to parse out the version from Cargo.toml in the CI
script.
