v0.1.4 - Revert changes from v0.1.3

Whatever was wrong with the swift.org server seems to have been resolved, so we should no longer skip the key import.

v0.1.3 - Temporarily disable loading GPG keys

There seems to be something up with how swift.org's server is returning the GPG keys that causes curl not to honor the Gzip content encoding, so for now just tell the Swiftly install script not to do that step.

v0.1.2 - Update Swiftly install script URL

The URL for Swiftly's install script has changed, so we've updated it.

v0.1.1 - Fix usage with AmazonLinux2 images

Full Changelog: v0.1.0...v0.1.1

v0.1.0 - First development release

This is the first (pre)release of this action.
