In `@dependency-registry/go.yaml`:
- Around line 357-361: The version constraint for the github.com/maypok86/otter
module is set to an invalid version that does not exist in the upstream
repository. Update the version field from ">=v2.3.0" to a valid version that
exists in the upstream repository, such as ">=v1.2.4" or ">=v1.2.0", which are
the actual available versions. This will ensure the dependency constraint
properly references versions that can be resolved.

As discussed we should use the Caching option available in Thunder rather than adopting this library.
