Subject: [PATCH 1/2] Build: Bump datamodel-code-generator from 0.63.0 to
 0.64.1

Regenerate open-api/rest-catalog-open-api.py with datamodel-code-generator
0.64.1. As of 0.64.0, optional primitive const fields no longer emit the
const value as an injected default, so the generated discriminator fields
(action/type) are now `Literal[...] | None = None`. Committing the
regenerated output keeps `make generate` + `git diff --exit-code` green.

Supersedes #16985.
