contrib/scripts: add Fedora version to podmain container name for "nm-code-format-container.sh"

Older branches, like "nm-1-32" will always be formatted with a
different, older clang-format version. Luckily we also have on "nm-1-32"
branch the "nm-code-format-container.sh" script, so we can still
reformat the sources using the container.

However, as the name of the container was always "nm-code-format",
we would have to re-generate the container when we switch between
branches. As the container really only depends on the Fedora version
(as the clang-format version is tied to the corresponding Fedora
version), let's include the Fedora version in the name of the container.
