fix(cli): read correct version

Previously, the CLI hardcoded "1.0.0" as the version string in two places (the root command and the generate-entry subcommand).

Introduce pkg/version, a minimal package that exposes a single variable Version, defaulting to "dev". The root command now references such a value; generate-entry does not need it al all

The Makefile computes the version at build time by running:

git describe --tags --always
This produces the exact tag name when HEAD is tagged, or --g when it is not, giving a precise description of the build relative to the nearest ancestor tag. If git is unavailable, the value falls back to "dev".

The resulting string is injected into the binary via:

-ldflags "-X github.com/89luca89/distrobox/pkg/version.Version=<value>" so that distrobox --version and distrobox generate-entry --version both report the exact version of the build.
