fix(deps): bump io.netty minimum version to 4.2.17.Final (GHSA-8c42-7qj2-3j46) (#404)

Update io.netty dependency floor from 4.2.16.Final to 4.2.17.Final to resolve
CORS Vary Header Overwrite cache poisoning/information disclosure vulnerability
(GHSA-8c42-7qj2-3j46) in io.netty:netty-codec-http.

Changes:
- Root build.gradle resolutionStrategy: bump version check and useVersion
- Update lockstep ext['netty.version'] in both example subprojects

Fixes Dependabot alert for io.netty:netty-codec-http vulnerable range
>= 4.2.0.Final, <= 4.2.16.Final, patched in 4.2.17.Final.
