Links to Julia documentation broken

[jonas-schulze]

Searching the documentation gives results for the language itself (which is awesome 🚀). However, the URL to the Julia docs are different from the ones to some packages, which JuliaHub doesn't distinguish:

• https://juliahub.com/ui/Documentation?q=relative%20error offers
• https://juliahub.com/docs/julia/THl1k/1.5.3/base/base/#Errors instead of
• https://docs.julialang.org/en/v1/base/base/#Errors

On top of that, 1.5.3 is not the most recent version of Julia, in case that's a hint of some other issue.

Fixed now.
