Trouble Shooting Docs out of date

Summary

The docs at https://docs.mattermost.com/install/troubleshooting.html are out of date.

Steps to reproduce

Go to bottom of the page, and see there’s a suggestion to use demo.mattermost.com. I dug around for it, and I’m guessing that it’s a service you no longer provide. If there’s another way to achieve the same result, it would be good to know!

Sorry if this is the wrong place to report this.

Hello, @rara

Thank you for highlighting that one out. Indeed, demo.mattermost.com is no longer in service and we encourage users to sign up for community.mattermost.com instead.

I will submit a PR to make the changes. Thanks again.
