Creating a new application using the @server template fails to take current package manager/version into account before trying to install dependencies.

? Choose template @server: TypeScript, Apollo (GraphQL), Express server
Ambiguous Syntax Error: Cannot find who to pick amongst the following alternatives:

  0. yarn install [--json] [--immutable] [--immutable-cache] [--check-cache] [--inline-builds] [--skip-builds]
  1. yarn install [--json] [--immutable] [--immutable-cache] [--check-cache] [--inline-builds] [--skip-builds]

Steps to reproduce the behavior:

1. mkdir repro-project && cd repro-project && yarn init -y
2. yarn set version berry
3. yarn create apollo-app my-app
4. Choose @server template
5. See error

Install uses the appropriate set of flags based on current package manager being used.
