[Bf-committers] Bump MacOS minimum requirements to 10.15 for Blender 3.5

[Brecht Van Lommel]

The purpose is to make Blender compatible with OS and library versions
specified in the VFX platform.

If we are compatible with more I don't see that as a deviation, and I'm not
aware of any compatibility issue that would be caused by us supporting
macOS 10.15.

We can formally write that in the commit message.
