feat: add ADBC connection profiles recipe

[ianmcook]

Adds a recipe demonstrating connection profiles (new in ADBC 23)

@prmoore77 This example uses GizmoSQL. Please have a look and let me know if there's anything you'd recommend doing differently!

@esadek Is it OK with you if I add this as one of the featured recipes at the top? How about replacing this exploratory data analysis one with this?

@ianmcook Fine with me. Want to keep the Arrow icon, or maybe switch it to a TOML icon?

Oh good call, I'll switch it to the TOML icon now

@prmoore77 I'm going to merge this now, but please share any comments here and I'll open a separate PR to address them

Hi @ianmcook - I'll try to check this out. Thanks for the heads up!
