fix: use browserHash for imports from node_modules

[patak-dev]

Description

Fix VitePress.

Revert a change introduced by #6758. See https://github.com/vitejs/vite/pull/6758/files#diff-9b81bb364c02eab9494a7d27a5effc400cacbffd3b8f349c192f890c37bfc83fR609

I wrote in the PR description:

Note: hash is used instead of browserHash for files excluded from optimization. This is unrelated to the PR, but as we need to re-test quite a bit to be able to merge this one, I think we could also check it in. hash only depends on the lock file, but should be enough here AFAICS

browserHash is actually needed here, as hash will be stable after a reload and these files will be stale.
