fix(graphql): drop ESM-broken _checkRequirements() so check works (#5654)

_checkRequirements() called require('axios'), which is undefined in ESM.
The ReferenceError was caught and reported the deps as missing, so
`npx codeceptjs check` failed with a false 'axios not installed' error.
Both call sites (container.js, init.js) guard with `if (._checkRequirements)`,
and missing deps already fail at import time, so the method is just removed.
