url link in README.md file leads to a page where the domain has expired.

Hi,

In README.md file there is url link: SOLID Web API
This link leads to a page where the domain has expired.
Maybe it would be much better to change where this link leads to https://platform.devmentors.io/courses/solidne-web-api

I had try to create pull request from separate branch but I was not able to create separate branch (lack of permissions :)).

Best regards
Piotr
