feature: expose the distribution type for use by features in choosing installation paths

[Common-utils has a bit of baseline distribution identification](https://github.com/devcontainers/features/blob/fbdc4556d519512736a8e2abfb3e03fcb2c9e0c7/src/common-utils/main.sh#L293) - enough to know what kind of package manger is in play, so that you can have a feature that doesn't just assume Debian and `apt-get` availability. Rather than making all feature developers replicate this bit of code, it would be hugely beneficial to drop it into a function and return a value so that `install.sh` scripts could use that information to know how to proceed with various distributions, or even to report that other distributions just "aren't supported" for that feature.

Comienza con la lógica de identificación de la distribución en src/common-utils/main.sh alrededor de la línea 293 y revisa cómo los scripts install.sh de las distintas funcionalidades seleccionan actualmente los gestores de paquetes. Define el valor de retorno reutilizable y su uso para las distribuciones compatibles y no compatibles, y después verifica las rutas de instalación afectadas en varias funcionalidades representativas.
