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.

 - `~1.3.0-0` is a **tilde** version range that includes _all_ pre-releases. It matches all versions `≥ 1.3.0-` and `< 1.4.0`.
 - `nightly` will install the latest nightly build.
-- `1.6-nightly` will install the latest nightly build for the upcoming 1.6 release. This version will only be available during certain phases of the Julia release cycle.
+- `1.7-nightly` will install the latest nightly build for the upcoming 1.7 release. This version will only be available during certain phases of the Julia release cycle.
 
 Internally the action uses node's semver package to resolve version ranges. Its [documentation](https://github.com/npm/node-semver#advanced-range-syntax) contains more details on the version range syntax. You can test what version will be selected for a given input in this JavaScript [REPL](https://repl.it/@SaschaMann/setup-julia-version-logic).
