Document error collector.diskdrive.md

The metric name prompted in this document is "disk_drive_info", but the name returned by the program is "diskdrive_info"

In addition, the document also indicates that the use of the WMI class is incorrect. The page displays the use of Win32_PerfRawData_DNS_DNS

If the document and the program return value names don't match, what's wrong? If the program returns the data, then I can change the document. But personally, I think there's something wrong with the data returned by the program.

Changing the program would result into a broken dashboard at end-user.

I would the docs here, unless the current metrics are totally wrong.
