Add production dependencies & build

* If the user does not specify the `arch` input, default to `${{ runner.arch }}` (instead of defaulting to `x64`)

* Add a CI workflow that tests the default arch (i.e. tests what happens when the user does not specify the `arch` input)

 ### 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.
