Update connections notation in tutorials

[mstechly]

Given the completion of PsiQ/qref#113, once new QREF version is released (i.e. higher than 0.6.2), we can update Bartiq to make use of the new, more concise way of defining connections.

Instead of:

connections = [{"source": "a.out", "target": "b.in"}]

we can now do:

connections = ["a.out -> b.in"]

Which should make examples slightly more pleasant to work with :)

Hi @mstechly, I’d like to work on this. The older connection dictionaries are still seemingly used in some of the tutorials such as 01_basic_example, 02_alias_sampling_basic, 03_advanced_examples, and the 2025 IEEE Quantum Week introduction. I would update only QREF connection entries to the concise notation and leave linked_params unchanged. I’ll also run the documentation and affected notebook checks across the repo. Would that cover the intended scope? I shall make the updates and share a PR for your review soon, I would appreciate it if you could assign this issue to me. Thanks!
