Update GitHub actions

Drop Python 2.7, as it is no longer available:

    Warning: The support for python 2.7 will be removed on June 19. Related issue: actions/setup-python#672
    Version 2.7 was not found in the local cache
    Error: The version '2.7' with architecture 'x64' was not found for Ubuntu 22.04.
    The list of all available versions can be found here: https://raw.githubusercontent.com/actions/python-versions/main/versions-manifest.json

Add Python 3.12 as its support was just added.

Fork macOS steps from Linux due to the ARM arch change:

- Rust 1.41 does not have a `aarch64-apple-darwin` version. The first Rust
  version that supports `aarch64-apple-darwin` is 1.49.0.
- Python 3.7 to 3.10 do not have a macOS ARM version in CI.
- Rust < 1.54 will fail on CI. See also See rust-lang/rust#107252:
