Installation error when using Yarn 4.x - "Unsupported option name ("--no-emoji")."

[harry643]

Summary

Yarn 4.x is now stable, but ghost-cli still assumes yarn 1.x is being used because during the ghost install local process, the yarn install --no-emoji command is used, which yarn 4.x does not allow.

Steps to Reproduce

corepack enable
yarn init
yarn set version 4.5.3
yarn add ghost-cli@latest
mkdir emptydir && cd emptydir
yarn exec ghost install local

I expected the command yarn exec ghost install local to succeed like it does when using yarn 1.x in the project:

$ yarn exec ghost install local
yarn exec v1.22.22
warning package.json: No license field

FYI - Yarn >=2 isn't really supported , so it's not unexpected to see issues like this.
