Update documentation on how to run with local services

[randomnetcat]

The documented instructions do happen to work for running Advisor (not sure why?) but I could not convince them to work with other applications (I tested learning-resources and registration-assistant). They result in the error:

Registration is not running or available via http://stage.foo.redhat.com:8004

Make sure to run `npm run start -- --port=8004` in the registration application directory to start it's webpack dev server and the bundle is built.

Based on the static script in learning-resources, I found that npx fec static --port=NNNN did work for all repositories.

Also, I found that the separator between the port and protocol is documented incorrectly; that is fixed here.

@randomnetcat The -- --port=0909 behaviour is broke atm. However, it will be fixed as soon as this PR is merged: https://github.com/RedHatInsights/frontend-components/pull/2007

Then the documentation should again be valid.

What you can do meanwhile is to add a port prop with the desired port to the fec.config.js. The part with LOCAL_APPS is still valid and should work as expected.

Ah, thank you, sorry.

The example happens to work because the protocol it attempts to specify is http, and that's already the default. See https://github.com/RedHatInsights/frontend-components/blob/fc61adcd088fe25997c36b8ef799f37dd7691739/packages/config-utils/src/proxy.ts#L70-L72
