goToDefinition for pattern ambient module no longer goes to implementation

[aaronadamsCA]

After switching to tsgo, command-clicking a .css import no longer opens the .css file. It just opens the pattern ambient module declaration.

Steps to reproduce

I'm pretty sure this test suite diff is already reproducing this issue:

typescript-go/testdata/baselines/reference/submodule/fourslash/goToDefinition/goToDefinitionCSSPatternAmbientModule.baseline.jsonc.diff

Lines 1 to 10 in d9178cc

	--- old.goToDefinitionCSSPatternAmbientModule.baseline.jsonc
	+++ new.goToDefinitionCSSPatternAmbientModule.baseline.jsonc
	@@= skipped -0, +0 lines =@@
	// === goToDefinition ===
	-// === /index.css ===
	-// [||]html { font-size: 16px; }
	-
	// === /types.ts ===
	// <|declare module [|"*.css"|] {
	// const styles: any;

Behavior with typescript@5.9

Go-to-Definition = Go-to-Implementation 👍

Behavior with tsgo

Go-to-Definition = Go-to-Type-Definition 👎
