v1.0.0-rc9

• Always set compiler_version parameter in the CodeGeneratorRequest to "(unknown)".
• Fix issue where buf mod update was unable to resolve dependencies from different remotes.
• Display the user-provided Buf Schema Registry remote, if specified, instead of the default within the buf login message.
• Fix issue where buf generate fails when the same plugin was specified more than once in a single invocation.
• Update the digest algorithm so that it encodes the name, lint, and breaking configuration encoded in the buf.yaml.
  When this change is deployed, users will observe the following:
  • Users on v0.43.0 or before will notice mismatched digest errors similar to the one described in #661.
  • Users on v0.44.0 or after will have their module cache invalidated, but it will repair itself automatically.
  • The buf.lock (across all versions) will reflect the new b3- digest values for new commits.
