Color scheme suggestion for documentation

[PieterLamers]

Although the documentation looks great in general, there is one thing I would certainly change: the color of attribute values. The green on grey is very low in contrast and therefore hard to read for me. BTW This also goes for eXist-db documentation, and I discovered some time ago that this may have to do with the color having been derived from a dark mode color scheme. Some examples of good contrast colors for xml in light mode are the BaseX wiki pages and the Oxygen standard color scheme.

yeah - agree - the green has too low contrast. Will find a better color.
