fix(renovate): enable scanning test directories for emulator images

The custom regex manager wasn't detecting emulator image dependencies
in test/e2e/internal/objectstore/ because Renovate's default ignorePaths
blocks test directories. Removed the `**/test/**` pattern while keeping
other sensible defaults to allow scanning test files.

Also fixed the regex pattern to handle the multi-line format where
renovate comments span three lines, and corrected all managerFilePatterns
to use the proper `/pattern$/` format.
