v1.38.0

• Add --http3 flag to buf curl which forces buf curl to use HTTP/3 as the transport.
• Fix issue with directory inputs for v2 workspaces where the specified directory was not itself
  a path to a module, but contained directories with modules, and the modules would not build.
• Stop creating empty buf.lock files when buf dep update does not find new dependencies
  to update and there is no existing buf.lock.
• Update buf push to push the license file or doc file (e.g. README.md, LICENSE) in the
  same directory as buf.yaml if a module does not have a license file or doc file in the
  module's directory.
• Fix constraints of --path flag for lint and breaking rules to avoid resolving all files
  within a module. This change can result in a performance improvement for large workspaces.
