21836	voltage-high and voltage-low keys replacement on power transformers	francois.lacombe	team	"Dear maintainers,

In #15367, deprecation of special voltages keys `voltage-high` and `voltage-low` has been forgotten.
It follows the approval of https://wiki.openstreetmap.org/wiki/Proposed_features/Transformer_extension_proposal in 2017

Wiki is up to date with dedicated pages for replacement guidelines.
* https://wiki.openstreetmap.org/wiki/Key:voltage-high
* https://wiki.openstreetmap.org/wiki/Key:voltage-low

Is it possible to raise a warning, at least like voltage=* in combination with power=transformer/transformer please?

By default, `voltage-high` and `voltage-low` are respectively replaceable by `voltage:primary` and `voltage:secondary`
When combined to `transformer=generator`, `voltage-high` and `voltage-low` are respectively replaceable by `voltage:secondary` and `voltage:primary` (primary and secondary are inverted).

Keep up with good work :)"	enhancement	closed	normal	22.08	Core validator		fixed	power, transformer, voltages
