"Prove your website, with DNS" instructions seem to be wrong

It seems to me that the instructions on keybase.io website and windows app say to add a TXT record where the name is blank or "@". I did this, but my website/domain verification would always fail. Once I took a look at what the command line was expecting, which seemed to be "_keybase", I changed the name to "_keybase" and it worked wonderfully - I've tried this with 3 more domains and the process and resolution was the same.

Compare the DNS verification instructions on keybase.io and in the Windows app with the command-line behavior described in the issue. Confirm that the TXT record name should be "_keybase" rather than blank or "@", then verify the corrected instructions across the reported domain-verification flow.
