[Bug]: MetaMask displays error messages across various screens

[sleepytanya]

Describe the bug

Occasionally, MetaMask users may notice error messages appearing across various screens, floating above the interface in a random manner. These errors primarily observed within the Settings section, though they have also made appearances on other screens. I'll make sure to update this ticket with more detailed information as it becomes available.

Expected behavior

Errors should be displayed in a predictable sequence, either within the console or as predefined error messages, to ensure clarity and ease of troubleshooting for users.

[Gudahtt]

The displayWarning function in actions.ts is responsible for this. This function is deprecated; replacing remaining usages will resolve this problem.

Though we'll have to find a more appropriate way to display each error on a case-by-case basis.

[gauthierpetetin]

We've reviewed this issue during refinement with @MetaMask/extension-platform . It seems the next step is clear as indicated by Gudahtt: remove occurrences of displayWarning function from the entire codebase. Changing the status to "ready for dev" to reflect that.
