test: remove vue plugin from optimize-deps playground

[sapphi-red]

Description

#11175

This test seems to be added by 1ea0168 and was intended to test whether the plugins will run on dep-optimization.
But since dep-optimization now uses esbuild instead of rollup, this test was outdated.
I changed this test's name to describe the actual thing we are now testing.
IIUC this test is now testing this part.

vite/packages/vite/src/node/optimizer/esbuildDepPlugin.ts

Lines 119 to 126 in d3c9c0b

	// externalize assets and commonly known non-js file types
	// See #8459 for more details about this require-import conversion
	build.onResolve(
	{
	filter: new RegExp(
	`\\.(` + allExternalTypes.join('|') + `)(\\?.*)?$`,
	),
	},
