acme troubleshooting: how to fix errored challenges

[jplitza]

I was looking for how to proceed if a Challenge is in "errored" state with the details pointing to a timeout. But all I could find in the troubleshooting guide (or really, The Internet) was what underlying problems could be in case Challenges or Orders are stuck in "pending". Thus, I deleted the Challenge, and a new one appeared. So maybe it should be mentioned that deleting Challenges is safe.

The word 'State' should be lowercase as it refers to the status field rather than a proper noun.

Suggested change

	In case your Challenge is in the State "errored", once you resolved the underlying issue, you can safely delete it. cert-manager will then request a new Challenge and retry.
