ci: update macOS runner version

[pendo324]

Issue #, if available:
Currently, we are using macOS 11 runners to build this archive. macOS 11 is deprecated, and we are no longer able to install our dependencies, which is causing runs to fail.

👏🏼 nice, I was looking where this was after your infra PR this morning. I thought I remembered there being one more spot we still ran these.
