fix(e2e): replace yaml package with section-aware string manipulation

Remove yaml dependency (not available in CI e2e-test job) and use
line-by-line parsing to replace the overrides section in
pnpm-workspace.yaml. This correctly handles projects using pnpm catalogs
by only modifying the overrides section without touching catalog entries.
