Add note about installing mono on Apple Silicon.

[harababurel]

I encountered an issue similar to a few existing ones (#792, #834, #846) but none of the suggestions or fixes resolved my problem. Eventually I discovered a solution in switching to the Intel version of mono instead of using the native one. Maybe this note can help others who run into the same issue.

Thanks!

Thanks for this. I think some good descriptions of how to get tools working in different environments is important.

However I wonder if we shouldn't move this into a Wiki article, and link to it from the README? That will make it easier to describe different OSes and distros. What do you think?

I'm going to close this now, I don't know if it is still relevant or accurate. Here is the content of the change, for anyone who wants it, or decides to add it to a wiki article:

Note: If installed on Apple Silicon using Homebrew, the native version of mono does not include MSBuild (current version requires .NET 5 but Apple Silicon support was added in .NET 6). So the package must be installed either via Rosetta or as a Cask. You can follow this answer to install an Intel version instead.
