Add some kind of error message when you are creating redirects, but don't have a plugin to act on them

[orta]

Description

I guess I expected by default gatsby would make client-side redirects, and then plugin APIs would allow more complex setups - however, a few months down the line I discovered that the redirect API is basically a NOOP unless you have a plugin like gatsby-plugin-client-side-redirect installed to actually do something.

Took a few bug reports to get there, so it might be worth having a check somewhere at build time that you have any plugins which can act on your redirects?

Steps to reproduce

Create a blank gatsby project, use createRedirect via createPages - see nothing happening

Expected result

A warning, or if you want to be really strict, an exception because it's a somewhat broken state

Actual result

No redirects, even though I was using the API right

Environment

N/A - on gatsby@^2.19.18

Hrmmmm, this might be me holding it wrong 🍡

Hi, thanks for the issue!

Seems reasonable to add some kind of warning (e.g. single line note) to the build output. In theory the API page already mentions that: https://www.gatsbyjs.org/docs/actions/#createRedirect

However, I understand that those pages are not too discover able. A dedicated documentation page would also be reasonable to solve this issue in my opinion.
