Avoid specifying error type since the default is unknown

[robertbrignull]

Since typescript 4.4 (release notes), values in a catch default to the unknown type. So we don't need to specify it, and there were a couple of places where we were explicitly using any that would be better off as unknown.

Discovered while working on #4056

Pull Request Overview

This PR updates TypeScript catch clauses to leverage the default unknown type introduced in TypeScript 4.4, removing explicit type annotations and replacing instances where any was used with the more type-safe default behavior.

• Removes explicit : unknown type annotations from catch clauses since they're now the default
• Updates test code to use getErrorMessage() helper instead of directly accessing .message property on error objects
• Improves type safety by avoiding explicit any typing in catch blocks
