fix: Add read-write permission to docker volume

[M3DZIK]

Fixes a permission denied error when using SELinux (for example on Fedora)

Without this, after downloading the recovery image, the error:

mv: cannot create regular file '/storage/base.dmg': Permission denied
install.sh: line 147: /storage/macos.version: Permission denied

and the recovery will download again and again.

":Z" should also work, but “:rw” works without any problems.

This is the first time I hear about a system where rw is not the default for volumes?

I'd prefer to keep the example compose files as brief as possible, so unless this is really needed I would like to avoid adding rw explicitly.

Are you sure this is not an issue with your specific SElinux config or some other modifications? Because I would have expected more people to report this problem if it was a common problem.

I haven't changed anything in the configuration, it's basically a fairly fresh system installation

@M3DZIK Very strange.. I never heard from any Fedora or podman user that they needed to add an explicit rw to their volumes to make them writeable.

I will keep an eye on it, and as soon as I get another report of this behaviour I will merge this pull request.

Okay, and just to clarify, I'm using docker, not podman.
