Problem with grpc_c.bundle

I think the problem is that there is some kind of regression bug between 1.42.0 and 1.43.1
If I search locally in my gem folder for grpc_c.bundle this is the result:

grpc-1.42.0/src/ruby/lib/grpc/grpc_c.bundle
grpc-1.42.0/src/ruby/ext/grpc/grpc_c.bundle
grpc-1.43.1-universal-darwin/src/ruby/lib/grpc/2.5/grpc_c.bundle
grpc-1.43.1-universal-darwin/src/ruby/lib/grpc/3.0/grpc_c.bundle
grpc-1.43.1-universal-darwin/src/ruby/lib/grpc/2.6/grpc_c.bundle
grpc-1.43.1-universal-darwin/src/ruby/lib/grpc/2.7/grpc_c.bundle

As you can see the 1.43.1 is again universal.
The file command gives me the following result:

ruby/2.7.3/gems
➜ file grpc-1.42.0/src/ruby/lib/grpc/grpc_c.bundle
grpc-1.42.0/src/ruby/lib/grpc/grpc_c.bundle: Mach-O 64-bit bundle arm64

ruby/2.7.3/gems
➜ file grpc-1.43.1-universal-darwin/src/ruby/lib/grpc/3.0/grpc_c.bundle
grpc-1.43.1-universal-darwin/src/ruby/lib/grpc/3.0/grpc_c.bundle: Mach-O 64-bit bundle x86_64

So you can see the 1.43.1 is x86_64 which is wrong

Make sure you include information that can help us debug (full error message, exception listing, stack trace, logs).

See TROUBLESHOOTING.md for how to diagnose problems better.
