Meta: Add build instructions for Void Linux

`git` and `bash` are most likely already installed, `bash` is part of
`base-system`, and `git` is required to pull the repository in the
first place, but they are not included in `base-minimal` or
`base-container`, and they ARE required for a successful build,
so I have added them regardless.

`qt6-tools-devel` and `qt6-wayland-devel` were not required to compile
and link Ladybird on my machine, but I have included them as they are
installed on the other Linux distributions.

 The build process requires at least python3.7; openSUSE Leap only features Python 3.6 as default, so it is recommendable to install package python311 and create a virtual environment (venv) in this case.
