The prepare-release.sh script updates Docker image version tags in *.yml
and templates/**/*.yml, but not in src/ci/components/*.jsonnet. Since
!1379 converted renovate-bot to Jsonnet, the generated renovate-bot.yml
gets its version bumped by semantic-release while the Jsonnet source is
left behind, creating a drift.

Also fix the existing drift: renovate-bot.jsonnet still had v3.15.0
while the generated YAML was bumped to v3.15.1 by the release commit.

Changes:
- prepare-release.sh: add src/ci/components/*.jsonnet to the glob
- .releaserc.json: add src/** to @semantic-release/git assets
- renovate-bot.jsonnet: fix v3.15.0 -> v3.15.1 drift
