Use the overrides field for npm and pnpm, or the resolutions field for yarn.

// package.json
{
  "overrides": {
    "@typescript-eslint/parser": "^4.0.0"
  }
}

In npm and pnpm, you can also match the version written in dependencies.

// package.json
{
  "dependencies": {
    "@typescript-eslint/parser": "^4.0.0"
  },
  "overrides": {
    "@typescript-eslint/parser": "$@typescript-eslint/parser"
  }
}
