docs(agents): remove references to skills that were never created

[mesutoezdil]

Three files referenced two skills, update-otel-collector-version and nvcf-self-hosted-local-dev, that were never created. Removed the dead references and pointed at existing docs instead.

Tested: version-bump script already guards each file with an existence check, so no behavior change. bash -n passes, no remaining references anywhere in the repo.

Refs: NO-REF

Local development guidance now references docs/dev/local-development.md. OTEL collector version-update documentation and the update script no longer reference or modify the removed version-update skill file.
