Clarify documentation on REGISTRY_KEY source

[panhania]

Registry key contents is quite ambiguous (and means something different from registry value contents), so the wording is clarified after consulting with @joachimmetz.

Furthermore, this also fixes the example that is not consistent with the description of the keys attribute:

A list of Windows Registry key paths (...)

I verified on my machine and HKEY_USERS\*\Software\Microsoft\Internet Explorer\TypedURLs users contains no subkeys, only values (e.g. url1 with content http://go.microsoft.com/fwlink/p/?LinkId=255141). Thus, the glob here will match no key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths proposed here on the other hand contains multiple subkeys (e.g. chrome.exe, pwsh.exe, mplayer2.exe) which contain values specifying the path (but are not consistent: some do it through the default value, some do it through value named Path).
