Fix macOS CI (#2238)

Fixes: #2237

CI has been broken for Mac since Homebrew pulled support for OpenSSL at
the specific version we're requiring. However this appears to be a
holdover from older versions of MacOS where Rosetta etc. were less well
supported, so in moving this forward we _should_ be able to upgrade as
well.
