Correct HTTP prefix for the local environment

[igorradovanov]

Description

Correct HTTP prefix for the local environment which doesn't support the HTTPS at the moment.
If the developer goes to the HTTPS version, as described in the docs, the next error occurs in the browser:

localhost sent an invalid response.
ERR_SSL_PROTOCOL_ERROR

This may confuse beginner developers.

How has this been tested?

Verified that Markdown is correctly formatted.
