[QGIS-Developer] MacOS Qt6 builds / Notarization

[Matthias Kuhn]

Dear all,

This has been merged and qt6 macos packages are now built from master and
for every pull request.

I also created a workflow to produce *notarized nightly builds* which can
be downloaded from the notarization repository
<https://github.com/opengisch/qgis-notarize/?tab=readme-ov-file#get-it>.

There is a permalink to the builds which also works without a github
account. I would propose that we include this on the download page (with a
name like QGIS 4 preview builds or similar).

Bests
