Fix Rosetta2 CocoaPods warning on Apple Silicon

[oblador]

Summary

The current warning assumes the ruby binary to be single arch, but the ruby version shipping with macOS is universal universal.arm64e-darwin20. This PR changes the check to search for arm64 in any position instead of just the beginning to fix false positives.

@barbieri and @mikehardy, can you please take a look at this? @fkgozali suggested you have more context on this fix.

Oh, interesting! Good catch+fix @oblador, thanks for the ping @sota000 - and while I will immediately defer to @barbieri if there were questions, this seems like it maintains the spirit of the original PR perfectly ("make sure ruby runs native not by translation") since a universal binary will run native if it can and there is a check for translation as the first clause.

[barbieri]

makes total sense 👍
