ci: clarify strict types generation in workflow (#475)

Update generate.yml workflow documentation to explicitly mention that
strict types (src/types-strict.ts) are generated alongside standard
types (types/api.d.ts) when the OpenAPI definition is synced.

The generation was already happening via generate-sdk.mjs, but wasn't
documented in the workflow comments or PR description template.
