Upgrade CI runner from macos-12 to macos-13

[qmuntal]

MacOS CI runners are deprecated and will be removed soon: actions/runner-images#10721.

In fact, macOS already entered the burnout period.

Grr, libcrypto.3.dylib does not exist in macos-14 (nor 13, nor 15...). In fact, the GH runner documentation says that those newer macOS images only ship with OpenSSL 1.1.1. OpenSSL 3 was probably included in macos-12 by mistake.

The problem is that there doesn't seem to be a libcrypto1.1.dylib file neither...

Maybe because just today macOS is migrating to OpenSSL 3 (https://github.com/actions/runner-images/blob/main/images/macos/macos-14-Readme.md) and things a bit messy. Will wait till tomorrow.

According to actions/runner-images#10817 macOS 13 will get OpenSSL 3, so I suppose we should end up pointing at that (rather than 14) to get oldest possible coverage?

Can we not brew install openssl@3?

actually yeah we may as well wait. Apparently "Image deployment will start on November 4 and will take 2-3 days."
