Mention in the Workers RPC Typescript documentation that you should use @cloudflare/workers-types/experimental.

Additional information

Spent a long time trying to figure out why I couldn't get the types to work with the new RPC functionality, I would always get:

Type 'PdfParserService' does not satisfy the constraint 'WorkerEntrypointBranded'.
  Property '[__WORKER_ENTRYPOINT_BRAND]' is missing in type 'PdfParserService' but required in type 'WorkerEntrypointBranded'.ts(2344)

Switching to @cloudflare/workers-types/experimental immediately fixed the issue.

👋 @johtso Thank you for the feedback about how we can make improvements with developers.cloudflare.com documentation. Closing this as it was determined that this conflicts with the preferred solution, which is already addressed in the docs. See comments in #20866 for more details.
