docs: update template

Fix #428
Fix #438

On https://webaim.org/resources/contrastchecker/ I changed the lightness/darkness to get AAA. It's less colorful as a result, maybe other colors could be found that both are darker/lighter but not sadder. 😅

I did a bit more work to prevent color changes on hovering (as the color was then not the nicest for contrast). I'm not sure the current choices are the best.

Main links on hovering, wavy underline decoration

Nav links on hovering, wavy underline decoration too

Thanks! Can you please apply to the other repositories?

@krlmlr it seems wiser to create and use a template package holding the configuration file, or do you prefer only configuration edits?

[krlmlr]

A template would be great, thanks!

[maelle]

could you please create an empty repo under r-dbi and give me write access? It could be called dbitemplate. Thank you!

[krlmlr]

Happy to accept a repo transfer for a repo you create 😉
