Small tweaks (#15)

* Directly add DocC dependency in package file

Since the package now only supports Swift 5.6 and higher we don't
need to check before adding the DocC dependency.

* Update README

Just a small change to show the latest app version in the example.

* Update Swift version

Since 5.6 support was previously dropped, updating the package files
to reflect that.
