Issue description

After finishing the creating a plugin using the Create New Plugin flow, a warning popup appear all red making it impossible to know what the warning is about.

Steps to reproduce

1. Go to Project Settings
2. Under the Plugins tab, create a new plugin
3. Fill up the detail (I created a C# script)
4. A warnning should appear after closing the creation window

Looking at the console, this could be the warning
Another resource is loaded from path 'res://addons/my_other_plugin/OtherPlugin.cs' (possible cyclic resource inclusion).

You probably had the Active now? option checked. In this case, the warning should look like this:

This is because C# scripts needs to be built before the plugin can be activated, so the Active now? option should always be unchecked for C# plugins. This is mentioned in the Making plugins documentation page.

This seems to be a rendering issue. I can reproduce it in Linux with v4.1.stable.mono.official [9704596] and v4.0.1.stable.mono.official [cacf499] but not with 4.0. I also can't reproduce with Single Window Mode.

Looks like it might be a regression from #73365. cc @bruvzg

Would it make sense to hide it if C# is selected?
Feels like a better UX if there is no case for the option to ever be enabled when C# is selected.

Yes, I agree the checkbox should be unchecked and disabled when you set the language to C#. A warning should also be displayed below to mention that the option isn't available for C# plugins. The UI has changed in 4.2: #76778
