Subject: [PATCH] 32-bit build for Linux (#14)

* Separated Linux build jobs from macOS and Windows build jobs.
  * 32-bit binaries for Linux must be built in a 32-bit container. I used Debian.
  * Hence, it made sense to use a 64-bit Debian container to build the 64-bit binaries, ditching Ubuntu.
* Used older versions of the checkout and upload actions for Linux builds.
  * The newer versions don't work in containers.
    * https://github.com/actions/runner/issues/2115
    * https://github.com/actions/upload-artifact/issues/361
    * https://github.com/actions/checkout/issues/1681
  * Consequently, the an older version of the corresponding download action must be used.
  * The older upload action doesn't recognise wildcard patters, so specified the `bin` directory to upload.
  * Did the same for the newer upload action for consistency.
* Moved `env` next to the step which requires the token.
* Tried to build the binaries in ARM containers, but the Linux runner is an AMD64 machine, so it didn't work.
  * The macOS runner which is an ARM machine does not have Docker, so couldn't use it, either.
