(GH-608) Fix package url for v0.102.0 & v0.103.0

Prior to this change, the URL building for versions of hugo was
deterministic as the URLs for the packages were set to a
project-specific standard. That URL creation began to fail for macOS in
[0.102.0] and for Windows in [0.103.0]. It does not fail for Linux
because the hugo releases for Linux continue to include the old package
naming as an alias.

This change:

- Updates the `get-os` function to take the hugo version as additional
  input, altering the return value based on the version.
- Updates the `get-arch` function to take the operating system name and
  hugo version as additional input, altering the return value based on
  both. Including the OS name is required for handling macOS.
- Fixes #608
- Fixes #605

[0.102.0]: https://github.com/gohugoio/hugo/releases/tag/v0.102.0
[0.103.0]: https://github.com/gohugoio/hugo/releases/tag/v0.103.0
