Corrected the deprecation diagnostic message to display the actual method name instead of the method type.
ModifiedcheckDeprecatedSignature andaddDeprecatedSuggestionWithSignature functions to extract and show the invoked method name.

Summary of Changes

IncheckDeprecatedSignature:
- Extract the invoked expression's name usingtryGetPropertyAccessOrIdentifierToString.
- If the name is missing and the expression is aPropertyAccessExpression, retrieve the name frompropAccess.name.getText().
- Fallback to<unknown> only if no name can be determined.
InaddDeprecatedSuggestionWithSignature:
- Use the extracted method name for deprecated diagnostics whendeprecatedEntity is falsy.
- Retains correct behavior for both signature-level and declaration-level deprecation messages.

Problem Solved

Before:'(): ZodObject<{ compilerOptions: ZodAny; }, $loose>' is deprecated
After:'passthrough()' is deprecated
The deprecation message now correctly shows the invoked method name instead of the type.

This needs a test, but is probably wrong as it is casting nodes around to any to extract text. The fix should probably in the caller ofaddDeprecatedSuggestionWithSignature as that func is just a helper that automates adding a diagnostic.
