for Device ZPA GH305 (SML), add a hint for required PIN

[Radoom]

First of all: !!! Thanks for your awesome work !!!

re PR: arendst/tasmota#

In Tasmota documentation / SmartMeter Interface
for Device ZPA GH305 (SML), please add a hint to the (maybe) required PIN to unlock this Device.
"Energy provider may have to supply a PIN code to enable output of additional data."

For this device a "PIN" may be required, which can be obtained from the grid provider / meter operator ("Messstellenbetreiber").
See here for example cases where this was necessary: arendst/Tasmota#18091

Will likely save others from some searching around if they directly get this hint.

@Radoom to reflect what is desired, please change issue Title to "for Device ZPA GH305 (SML), add a hint for required PIN"

[Radoom]

Done :-)

Great!
Could I encourage you to implemented the proposed change yourself too?
The required effort is about as much as changing the issue title :)
I'm happy to assist you in case of questions.

[Radoom]

Basically yes sure...however, I have no clue how and where I'd have to do that. Never "contributed" a single character to any project except for testing feedback/bug reports.
