Change the ABI to glibmm-2.58

So we can use the 2.55/56 version numbers for more stable releases.
We don't need to release a stable ABI-parallel glibmm until
we need to release gtkmm 4.0, and that won't happen until GTK+ 4.0.0
happens, and we don't know when that might be.

We did this twice before:
