fix: remove platform-dependent args test from vpr snap test

Drop the `vpr greet --arg1 value1` test case because pnpm quotes
arguments differently on Windows (`"--arg1" "value1"` vs `--arg1
value1`), causing CI failures. Args passthrough is already covered
by the existing command-run-without-vite-plus test (win32-ignored).
