rename references of "coder cloud"

[bpmct]

Corresponds with coder/cloud-agent#12

Unrelated to your change, but under Hiring there's a link to a job posting which is still visible, but not shown on the main listing page, so I'm not sure if it was taken down - in any case I'd suggest linking to the main page rather than a specific posting, and making the language more generic (something like "Coder is hiring! See our jobs page") so that it's not referring to a specific position, as the open positions change over time

Maybe @cami333 has thoughts here

@jawnsy I would prefer to just put the careers page link as you suggested. :)

LGTM! Re: Jonathan's change. I'll open a separate PR for that.
