fix(e2e): Add p-map override to fix React Router 7 test builds (#18068)

Fixes ERR_REQUIRE_ESM error in React Router 7 E2E tests by pinning p-map
to v4 which supports CommonJS, resolving incompatibility with
@react-router/dev v7.5+ that uses require() instead of dynamic import().

React Router should fix this upstream, this is a workaround now.
