Support HMR in our samples

[JamesBurnside]

What

• Install hot module reload for react & webpack packages
• Set webpack port to 443 to support HMR in codespaces as per https://github.com/orgs/community/discussions/11524#discussioncomment-2176952

Why

Support hot module reload in our samples (no more refreshing the page, rejoining the call etc. for small changes)

How Tested

Ran locally in codespaces and could hot reload isolated modules
