Enter key in IME mode would trigger search in search bar

[Jorrrmungandr]

Describe the bug

When composing in Chinese IME (maybe also in other East Asian language IME), pressing enter key should finish composing rather than trigger a search. This problem has been fixed in docsearch 3.7.0 (algolia/autocomplete#1238), but the version in vitepress is 3.6.2. I've locally updated the dependencies and it works as expected. I wonder if I could submit a PR to address this issue?
