Homebrew doesn't provide bottles for macOS 11 anymore, causing
dependencies to be compiled in CI which takes approximately 173 years.
Therefore, upgrade to macOS 12 and
- remove DEVELOPER_DIR environment variable which caused problems but
its removal doesn't appear to break anything
- upgrade npm because versions before 10.2.2 use Python's distutils
package which was removed in Python 12. See
