Spurious Link to Database Manager

[briangithex]

Reproduction steps:

1. Visit https://docs.microsoft.com/en-us/iis/extensions/iis-compression/iis-compression-overview
2. On the left sidebar, "IIS Database Manager" (under "Extensions") links to https://docs.microsoft.com/en-us/ . This should probably be outright removed, since the sidebar already has a "Database Manager" (under "Extensions").
