[Tagging] Add transformer=distribution on minor_distribution power substations nodes

Good evening everybody

As power mapping goes on in France, we use to find some power substation in
street cabinets like in many countries.
Those cabinets often host a single transformer to step down voltage for
households (and its a power substation since there are switches with the
transformer in the cabinet).

Since some figures about the transformer can be got on the cabinet, it may
be useful to add some *optional* tags to minor distribution substations
mapped with a single node: (street cabinets are often described as a single
node because of their small size)
voltage:primary=<transformer primary voltage if known>
voltage:secondary=<transformer secondary voltage if known>
rating=<transformer rating if known>

Example : https://www.openstreetmap.org/node/5716114593

This would mix the place (power substation) with the device inside (the
power transformer) for minor distribution substations on nodes only as we
use to do for transformers on power poles.

It's also possible to describe the cabinet + substation as an area and the
transformer as a node inside, like when the substation is in a building but
this may clutter the map.
The substation : https://www.openstreetmap.org/way/70564498
The transformer inside : https://www.openstreetmap.org/node/5631393069

How do you feel about this optional improvement?

If everyone agree with it, or no further comments, examples on
power=substation and power=transformer wiki pages will be updated
accordingly in 15 days.
I think there is no need of formal vote for this one.

Feel free to comment and ask
All the best
