Change landuse=railway default color in JOSM style

[Cartographer10]

Landuse=railway is currently tagged with a grey line color and fill. This is the same color as untagged ways. I therefore propose to change the rendering in JOSM to another color, for example purple, just like railway on Carto.

I often confuse landuse=railway for untagged ways when working on landuse next to those railways. Beside that, landuse=railway is almost not visible in JOSM because of they grey color, even without other landuse mapped around it.

In 18559/josm:

fix #22359 - Change default color of landuse=railway and landuse=quarry as they were too similar to untagged ways color (#808080)
