Update DS18x20.md

Add the comment - "Note: Experience has shown that the 4k7 is necessary even for a single DS18x20 sensor".

If the 4k7 is added then this command is not required so maybe a better change would be to remove the reference to the command and to add a note making the 4k7 mandatory.

how much experience are talking about? dozen sensors? 50?

I've only a few (4) DS18B20 running without pullups. When SetOption74 was set, I had no problems till now.

Any updates on this? Seems reasonable to merge with this warning imo; otherwise, is there a better wording you'd like to see?
