Remove unnecessary verbose message from ConvertTo-Json  #7486

In #6392 this line below was added to the ConvertTo-Json cmdlet.

WriteVerbose(StringUtil.Format(UtilityCommonStrings.ConvertToJsonProcessValueVerboseMessae, t.Name, depth));

This produces unnecessarily verbose output when converting complex objects to json.

In my opinion, this verbosity doesn't add any value and clutters up script output.

VERBOSE: Processing object of type [OrderedDictionary] at depth 0
VERBOSE: Processing object of type [PSCustomObject] at depth 1
VERBOSE: Processing object of type [OrderedDictionary] at depth 0
VERBOSE: Processing object of type [PSCustomObject] at depth 1

I propose either removing this entry entirely or changing it to WriteDebug to keep the noise down.
