remove update webpack config

[benschac]

What does this PR do and why?

After the first diff, the next.js server was logging this error:

[
  {
    "instancePath": "",
    "schemaPath": "#/additionalProperties",
    "keyword": "additionalProperties",
    "params": {
      "additionalProperty": "webpack5"
    },
    "message": "must NOT have additional properties"
  }
]

after googling, removing the webpack5 config seemed like the right fix.

The error was resolved. More here: vercel/next.js#39161
