chore(release): add a simple script for testing the release on *nix

CONTRIBUTING.md

     * On a **Windows** machine, run `garden dev --hot=vote` in the `vote` example project.
         * Change a file in the `vote` service and verify that the hot reload was successful.
         * Open the dashboard, verify that the initial page loads without errors.
+    * On **macOS** or **Linux**, run the `./bin/test-release <version>` script. The script runs some simple tests to sanity check the release.
 5. Go to our Github [Releases page](https://github.com/garden-io/garden/releases) and click the **Edit** button for the draft just created from CI. Note that for drafts, a new one is always created instead of replacing a previous one.
 6. Write release notes. The notes should give an overview of the release and mention all relevant features. They should also **acknowledge all external contributors** and contain the changelog for that release.
     * To generate a changelog for just that tag, run `git-chglog <tag-name>`
