changed wiki.css to resolve anchor hiding behind header

[Ash-KODES]

Made changes in the wiki.css file to resolve the issue of the target element hiding behind the fixed header.
I changed the css code of the hidden anchor(which was the main target of the link icon), by setting the values of padding-top and margin-top css properties, to offset it according to the height of the header.

Fixes #10744

Hi, this looks super. I wonder if one of the issues here was that the "ribbon" across the top (in lavender color) is pushing the navbar down. If that's the case, then when the ribbon is removed, these anchors will be a little too low, right?

So I have 2 questions:

1. do you think my guess is true about the ribbon (shall we try removing it for now to test?)
2. even if anchors are too low, that's much better than too high, right? I mean, maybe this solution is good even so! What do you think?

I saved the content of the ribbon (which can be modified by admins) so you can see the code. It does include some CSS:
