Dead link in README.md for Get a Show

[jpdavalos423]

The link under the Features section and Shows subsection no longer works.

Dead Link: https://developer.spotify.com/documentation/web-api/reference/shows/get-a-show

I believe this is the link for the replacement: https://developer.spotify.com/documentation/web-api/reference/get-a-show

Relevant Line:
