deprocate getProductPrices query in front end (#10397)

**TLDR:**
Deprecate getProductPrices in the frontEnd and replace it with
BillingBaseProductPrices.

**In order to test:**

- Have the environment variable IS_BILLING_ENABLED set to true and add
the other required environment variables for Billing to work
- Do a database reset (to ensure that the new feature flag is properly
added and that the billing tables are created)
- Run the command: npx nx run twenty-server:command
billing:sync-plans-data (if you don't do that the products and prices
will not be present in the database)
- Run the server , the frontend, the worker, and the stripe listen
command (stripe listen --forward-to
http://localhost:3000/billing/webhooks)
- Buy a subscription for acme workspace the choose your plan should be
using the new front end endpoint
