## Summary
- Updated `webpack` (and all related packages) to v5 in
`react-devtools-*` packages.
- I haven't touched any `TODO (Webpack 5)`. Tried to poke it, but each
my attempt failed and parsing hook names feature stopped working. I will
work on this in a separate PR.
- This work is one of prerequisites for updating Firefox extension to
manifests v3

## How did you test this change?
Tested on all surfaces, explicitly checked that parsing hook names
feature still works.
We have a currently unreproducible flaky e2e test. This PR captures snapshots on e2e test failures so we can better debug flaky e2e tests that don't fail locally.
Modified the `run_devtools_e2e_tests` script so that you can pass in a React version. If you pass in a version, it will build the DevTools shell and run the e2e tests with that version.
