Update README version during release

The release workflow bumps the version in gradle.properties and the
CHANGELOG but left the dependency snippet in README.md pinned to the
previous release, so the documented version drifted behind each release.

Rewrite the README dependency coordinate to the release version and
include README.md in the release commit.
