Add production dependencies & build

Setting the `arch` input to `aarch64` will install `aarch64` binaries,
intended to be used on aarch64-based self-hosted runners.

Please note that we currently don't run test builds on that
architecture, so we cannot guarantee that the input won't break
randomly, although there is no reason why it would.

In a future update, we may choose a default architecture based on the
arch of the runner.

Thanks to @giordano for providing a self-hosted runner for testing.

 ### versioninfo
 
-By default, only a brief version identifier is printed in the run log. You can display the full `versioninfo` by adding `show-versioninfo`.
-Here's an example that prints this information just for `nightly`:
+By default, only the output of `julia --version` is printed as verification that Julia has been installed for stable versions of Julia.
+`InteractiveUtils.versioninfo()` is run by default for nightly builds.
 
-```yaml
-    - uses: julia-actions/setup-julia@v1
-      with:
-        version: ${{ matrix.version }}
-        arch: ${{ matrix.arch }}
-        show-versioninfo: ${{ matrix.version == 'nightly' }}
- ```
- 
-You use `'true'` if you want it printed for all Julia versions.
+Starting Julia and printing the full versioninfo takes a significant amount of time (1s or ~10% of the total build time in testing), so you may not want to run it in every build, in particular on paid runners as this cost will add up quickly.
+However, `julia --version` does not provide sufficient information to know which commit a nightly binary was built from, therefore it is useful to show the full versioninfo on nightly builds regardless.
+
+You can override this behaviour by changing the input to `never` if you never want to run `InteractiveUtils.versioninfo()` or to `true` if you always want to run `InteractiveUtils.versioninfo()`, even on stable Julia builds.
