fix(compiler): expected type to be "Array", but got "Array" instead (#…
…6571) Fixes #3822 I considered a few approaches and concluded that the lightest one would be passing the parent type into the validation function, and then using it (if not None) in the diagnostic message. Updated the validation function calls accordingly. Currently supported only for the `Equal` and `NotEqual` binary operators ## Checklist - [x] Title matches [Winglang's style guide](https://www.winglang.io/contributing/start-here/pull_requests#how-are-pull-request-titles-formatted) - [x] Description explains motivation and solution - [x] Tests added (always) - [ ] Docs updated (only required for features) - [ ] Added `pr/e2e-full` label if this feature requires end-to-end testing *By submitting this pull request, I confirm that my contribution is made under the terms of the [Wing Cloud Contribution License](https://github.com/winglang/wing/blob/main/CONTRIBUTION_LICENSE.md)*.
