Close all (or as many as possible) open PRs!

[merelcht]

Description

Let's do a bit of housekeeping in the coming sprint(s) and close/merge as many open PRs as possible.

Context

Focussing on the kedro repo: some PRs have been open for a long time. Let's close or merge them, so we get our repo in a healthier looking state.

• [Proposal] - Add KedroPipelineError and provide better error message for invalid node/pipeline definition #2734
• e2e-test for %load_node magic #3528
• Add documentation about correct usage of configure_project #3707
• Remove the copying hack and add proper params querying capabilities in the DataCatalog #3732 @merelcht Closed, because it's a breaking change and no agreement on approach. This should instead be tackled during sprint work as part of either the catalog redesign or performance improvements.
• Add docs databricks asset bundles #3744 -> there's kedro-databricks now, so might not be needed to merge this.
• Tag names limitation #3785
• Update contributing and README with new support scheme #3819
• Create a docs page about adding code beyond starter files #3852
• Unpack dictionary parameters #3905 -> Needs more work, not close to being merged.

Next we can focus on kedro-plugins
