Allow the Provider Configuration section to be closed by default

Hello,
I've checked the AiProviderFormHelper.php file, and I think we need to add '#open' => FALSE, in the generateAiProvidersForm function for the detail element to close by default.

Thank you!

I added a MR to add this functionality.
Whether or not the Provider Configuration fieldset is open by default or not, is managed via config. The default setting for this config is to remain open, to keep backwards compatibility.

Added patch file for the current state of the MR, for composer based patching workflows.

@svendecabooter This works in my testing. I made some minor code cleanup adjustments and merged it. This will go out in the next release. Thank you!
