Swap back default macOS and tvOS SDK versions

These seem to have been accidentally switched around in https://github.com/bazelbuild/bazel/commit/8a1584e77c5c71e98a8cac87e6c5df6ee5d94c63, which caused the following error message to show when I try to build any C++ code on my Sonoma M1 Macbook:

    clang: error: invalid version number in '-mmacosx-version-min=9.0'

Turns out my XCode was out of date anyway, but this should probably still be fixed.
