v1.67.0

• Fix LSP not skipping buf.build/docs links for lint rules from check plugins and policies.
• Fix buf dep graph --format json silently dropping dependencies when a dependency was already seen.
• Add support for --rbs_out as a protoc_builtin plugin (requires protoc v34.0+).
• Add relevant links from CEL LSP hover documentation to either <celbyexample.com> or <protovalidate.com>
• Add OpenBSD and FreeBSD release binaries for amd64 and arm64.
• Skip writing unchanged output files in buf generate to preserve modification times
• Update buf beta registry plugin delete to prompt the user for deletion, matching the UX of the other deletion commands. Use --force to restore the old behavior.
