chore(www): sidebar add hover effect

[oddvernes]

resolves #4561

added --dsc-link-background--active as background on hover as requested in parent issue.
Also there was non-functioning code to make the left border of current page blue on hover which i fixed (but not sure if legacy from when there was a line along the full menu).

Should there be a hover on the toc menu as well or no?

Not a fan of the hover on an active item 🤔

Is the same background as for inactive ones not good enough?

Yea as mentioned i 'fixed' some broken css but its probably legacy stuff that was supposed to be removed. Perhaps no hover on current page is better (its not something you are supposed to click on anyway)

I think yes, why not :)
