Describe the issue you're reporting

Since the cmd/githubgen tool will soon be used in https://github.com/open-telemetry/opentelemetry-collector (see open-telemetry/opentelemetry-collector#11756), I propose to move the tool to https://github.com/open-telemetry/opentelemetry-go-build-tools/ so that it can be maintained in a more central place.

The tool would also need to be slightly parameterized to be able for it to work for both collector-core and -contrib (e.g. file templates shall be configured from the outside and an ignore list would also be helpful to be able to ignore test components for example).
