Missing signs, wrong SVG files

[fabianh001]

I'm currently investigating Mapillary's traffic signs and figured out that there are various SVGs incorrect or completely missing.
For example, regulatory--end-of-pedestrians-only--g2 and regulatory--end-of-pedestrians-only--g3 contain incorrect pedestrian zone signs, instead end-of-pedestrian-only signs.

What is the best way to contribute and resolve upcoming errors?
