Validator complain about unknown values for capacity

[mdk]

What steps will reproduce the problem?

1. Draw an parking place aminity=parking & parking=surface & capacity=50
2. Validate

What is the expected result?

No validator messages

What happens instead?

Preset do not contain property value: value '50' for key 'capacity' is not in the preset.
The same in a small area I currently editing: 11, 55, 150

A similar problem happens with the key 'cables'. But there are explicit values in the presets.
But there are several false positive like '4'. In Switzerland we have two different power system. The 'normal' which has multiple of 3 cables and the 'railway' power which has '4' (according to taginfo over 4000 times). And sometimes the use the same poles or towers. So '7' and more often '10' are also normal.

In 10361/josm:

fix #12948 - slightly improve cables, circuits and capacity presets and warnings; partly a regression of r10330
