chore: minor housekeeping

[fry69]

• remove leftover www/dev.ts from Vite conversion
• plugin-vite tests use only local folders on windows (like fix(init): correct temporary directory creation in tests #3425)

Reason: Leftover tmp_vite* folders are piling up in my filesystem inside the repository

LGTM

CI says "no" though. Not sure why.

[
  'error: Failed loading https://registry.npmjs.org/fdir for package "fdir"',
  "",
  "Caused by:",
  '    npm package not found in cache: "fdir", --cached-only is specified.'
]

This does not actually work as I thought it would (a recurring theme).

The local folders seem to be necessary also on Linux and on macOS. I am reverting now and looking for a solution to clean the mess up after failed test leave dangling tmp_vite folders around.

I kind of gave up on this, as deno.test.afterAll() seems also not to be doing what I thought it would do. Unsure if that is a bug or intentional. See my attempt here -> main...fry69:fresh:fry69/fix-vite-tmp-folders

My hypothesis is that deno.test.afterAll() does not seem to fire in parallel mode, probably because test fail during setup. But this is just a guess.

FWIW, I leave this PR open for comments.
