Update samples to latest Uno.Sdk 5.3

[agneszitte]

Now that version 5.3 has been released, we need to update the samples to the latest stable Uno.Sdk 5.3.

Here's the markdown table with the specified columns:

✅: DONE
👀: In review
⌛: In progress
🚧: Needs re-work (ci errors, additional review comments,...)
🅱️: Blocked (+ issue and comment with the reason)
❌: Cannot be updated (+ comment with the reason)
⏸️: On hold (Not a priority to update older samples at the moment as it needs to migrate to the single structure at the same time)
📋: To-Do

Authentication with OpenID Connect (OIDC)	@morning4coffe-dev	🅱️/⏸️		(Let's put it on hold for now) The sample doesn't seem to work outside of WASM. Fails on WebAuthenticationBroker.GetCurrentApplicationCallbackUri(); not implemented? We could update this with the newer Extension OIDC option?
