typescript with esm does not work with certain tsconfig.json values

[AtofStryker]

Current behavior

Cypress is unable to run typescript/esm projects when certain values are set in the tsconfig.json. This tsconfig.json does not work with ESM when setting type: "module" in the package.json.

{
    "compilerOptions": {
      "target": "es5",
      "lib": ["dom", "dom.iterable", "esnext"],
      "allowJs": true,
      "skipLibCheck": true,
      "strict": true,
      "forceConsistentCasingInFileNames": true,
      "noEmit": true,
      "esModuleInterop": true,
      "module": "es6",
      "moduleResolution": "node",
      "resolveJsonModule": true,
      "isolatedModules": true,
      "jsx": "preserve",
      "incremental": true,
      "plugins": [{ "name": "next" }],
      "paths": { "@/*": ["./*"] }
    },
    "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx", ".next/types/**/*.ts"],
    "exclude": ["node_modules"]
  }

To workaround this issue, either comment out allowJs or bump the target to ES6 or greater

Desired behavior

Cypress should be able to run ESM with typescript regardless of the values in my tsconfig.json

This is identical to the tsconfig.json found in the nextjs@14 scaffolding besides the module and moduleResolution. The same issue would still apply if type: "module" were configured for #27731 reproduction.
