platforms-serverless/firebase-functions test: update outdated firebase-admin dependency

[Jolg42]

Found through #3228

Updating TypeScript to version 4.9.4 fails with

• platforms-serverless (firebase-functions, library, ubuntu-latest): node_modules/@types/node/globals.d.ts#L85

   Subsequent variable declarations must have the same type. Variable 'AbortSignal' must be of type '*** new (): AbortSignal; prototype: AbortSignal; abort(reason?: any): AbortSignal; timeout(milliseconds: number): AbortSignal; ***', but here has type '*** new (): AbortSignal; prototype: AbortSignal; ***'.
  

• platforms-serverless (firebase-functions, binary, ubuntu-latest): node_modules/@types/node/globals.d.ts#L85

   Subsequent variable declarations must have the same type. Variable 'AbortSignal' must be of type '*** new (): AbortSignal; prototype: AbortSignal; abort(reason?: any): AbortSignal; timeout(milliseconds: number): AbortSignal; ***', but here has type '*** new (): AbortSignal; prototype: AbortSignal; ***'.
  

Problem

• https://github.com/prisma/ecosystem-tests/blob/dev/platforms-serverless/firebase-functions/functions/package.json uses "firebase-admin": "10.3.0", should be updated, see issue fix(deps): update dependency firebase-admin to v11.9.0 #2880
