Onboard Renovate for Develocity plugin and Gradle wrapper upgrades

Adds .github/renovate.json5 so this repo manages its own Develocity
Gradle plugin version (across the workflow YAML, build-scan.ts, the
setup-gradle docs, the sample settings.gradle / build.gradle files,
and the init-script test groovy files) and Gradle wrapper bumps in the
five sample directories that previously had wrappers maintained
externally.

Renovate is scoped narrowly via enabledManagers so it does not overlap
with the npm, github-actions, and Maven-coordinate Gradle updates that
Dependabot continues to handle through .github/dependabot.yml.
