🐰 A Julia driver hops into view,
With LibPQ to connect through and through,
Grid cards and guides, so shiny and new,

Let's discuss https://github.com/crate/tech-content/issues/124#issuecomment-3485676563 before merging

[amotl]

I think it's nice to have a dedicated page about Julia, so that all downstream entities (humans and machines) can easily learn how to connect to CrateDB using the PostgreSQL interface, and use a ready-to-run example to exercise it right away.

In the long run, this will also improve network effects, because CrateDB gains a dedicated representation within the corresponding search- and vectorspaces.

Currently, relevant search keywords like cratedb julia will not yield concise results, but this will improve a few days after merging this patch.

In `@docs/connect/julia/index.md`:
- Line 28: Update the cloud connection example that constructs the LibPQ
connection string so it omits the database path component; locate the
LibPQ.Connection call (the line assigning conn = LibPQ.Connection(...)) that
currently contains "/doc" in the URL and remove "/doc" so the URI ends with
"/?sslmode=require", matching the local example and other language docs and
CrateDB's schema model.

thx!

same comment as in the other PR, to not indicate this is only for Cloud.
