make: Build a file-based catalog

Since OLM is deprecating the SQLite based catalog we are currently
using, while at the same time, the SQLite based catalogs have issues
interacting with OpenShift clusters that implement the recent PSA
changes, let's switch to file-based catalog:
    https://olm.operatorframework.io/docs/reference/file-based-catalogs/

Most of the work is done by the "opm render" command except for some
metadata that is stored at catalog/preamble.json, for example the icon.
