[FEATURE] different default link color for dark mode

[dekoza]

Currently the links in dark mode have too little contrast, they should be a bit brighter.
Right now the color is rgb(32, 107, 196) and it should be rather rgb(88, 166, 255) - like in GitHub which has darker backgrounds which gives even better contrast.

This is how links inside table look like; added class text-decoration-none:
