fix: do not append version query param when scanning for dependencies

[shYkiSto]

Description

Ensure dependency scanner does not skip over bare imports for which there's an alias to an absolute path configured in the vite.config.js. Previously this would trigger expensive "full reloads", and invalidate all of the modules in the module graph when a missing dependency is found while "crawling" (see optimizer.ts). This does not seem to be necessary in this case, as it should be able to figure out all of the used dependencies during the initial pass.

This used to happen because a version query param was appended to the resolved path, when resolving aliased module id (an absolute path, see resolve.ts). In which case the dependency optimizer would skip over such dependencies as it would not match the regex that specifically checks that the path ends with a file extension (see isOptimizable() @ utils.ts).

Additional context

I've added a missing setup to handle this test scenario in the optimize-deps playground, but could not figure out a reliable way to check for unnecessary full reloads in tests.

FWIW, the existing test suite started to fail because of unexpected reloads, and to fix it I had to add the index.html to the entries, so all of the dependencies are pre-bundled for the first page load.
