feat: port all tests from v9 to v10

Describe the feature you’d like to request

We have a lot of tests that are outdated and using v9. We should have them all in v10-structure.

Good intro if you are curious about contributing to tRPC.

Describe the solution you’d like to see

Instructions

• https://github.com/trpc/trpc/blob/main/CONTRIBUTING.md
• Rewrite all of https://github.com/trpc/trpc/tree/main/packages/tests/server/interop to a nice v10 equivalent (the v10 tests are in the folder above)
• Some have equivalents already
• They can be done one-by-one
• Improvements on the general testing structure is also welcome

Example

1. Copy /packages/tests/server/interop/outputParser.test.ts -> /packages/tests/server/outputParser.test.ts
2. Replace legacyRouterToServerAndClient with routerToServerAndClientNew
3. Rewrite the routers using tRPC 10
4. Rewrite the calls using tRPC 10

Get paid

• We can pay $10-15 per test file rewritten if done well. $50 for bigger ones (like subscriptions and WebSockets).
• Once you get into the flow, it might not take more than 5 minutes per test file.

I think my PR accidentally closed this whole issue 😅 I think there are some tests left to port over.

I’ll give a hand with this one 😄 Making one by one seems a good idea since other people might want to help as well.

Currently checking validators.test.ts.
