Simplify internal resolver in dev

[bluwy]

Changes

This cleans up our .jsx -> .tsx handling. The code is removed since it's already handled at

astro/packages/astro/src/core/util.ts

Lines 176 to 179 in 36253f4

	// Try resolve jsx to tsx
	if (!resultId && id.endsWith('.jsx')) {
	resultId = await loader.resolveId(id.slice(0, -4), undefined);
	}

This should prevent Vite's perf PR (vitejs/vite#12450) from breaking for a specific case, where the user project imports .tsx components that's outside of the project root.

Testing

n/a. Existing tests should pass.

Docs

n/a. code refactor and cleanup.
