docs: Move INSTALL.in to INSTALL.md

We hadn’t been substituting the version number in properly for a while,
so maybe just abandon that approach and rewrite the instructions to not
refer to a specific version number.

This simplifies things a bit, and means the install instructions can be
read online in GitLab.
