Added volume bind option SELinux label :z :Z

Added unsupported volume bind option SELinux label `:z` and `:Z` in v2.

It is a regression compared to v1 written in Python.

The v2 uses the compose-spec/compose-go to parse Compose YAML
specification files but there was missing support for volume bind option
SELinux label `:z` and `:Z` in parser. It is fixed in:

- https://github.com/compose-spec/compose-go/pull/213

It fixes #9072
