GitHub link in docs points to ChainRulesCore.jl

[haakon-e]

I'm checking out this package's awesome documentation for inspiration for my own work and noticed a tiny, but potentially confusing issue for certain new users (like myself).

If I'm in the docs[^1], and click the "GitHub" icon at the top right of the page, I'm directed to the ChainRulesCore.jl instead of the ChainRules.jl source code.

Since the docs is about the ChainRules.jl package, I would expect the link to point to the ChainRules.jl source code.

[^1]: I now realize the docs is hosted by ChainRulesCore.jl. This is likely why the link points where it does.
