Describe the solution

In Wrangler v3, --local-protocol=https is currently unsupported during wrangler dev and wrangler pages dev:

https://github.com/cloudflare/workers-sdk/blob/main/packages/wrangler/src/dev/miniflare.ts#L374-L378

Miniflare 3 does not support HTTPS servers yet, starting an HTTP server instead...

However, Miniflare v3 specifically describes HTTPS support in its documentation:

https://miniflare.dev/get-started/cli#https-server

I can't find any existing issue tracking this missing v3 feature, so I wanted to start one, as it's important for certain use cases.
