[web] Ignore opaque-ke WASM modules in .flowconfig
Summary:
The JS in these folders is codegenned, so there's no point having Flow check them.
Depends on D7633
Test Plan:
- Build opaque-ke: cd web/opaque-ke-wasm && yarn build
- Run cd web && yarn flow and make sure there are no errors from opaque-ke-wasm artifacts
