It seems VitePress was relying on the auto injection of ?import for @vite-ignoreed imports that was removed by #14851.

I wonder if a mention to the upcoming Vitest 1.0 should be mentioned? I mean the first official stable release of Vitest (which Vite uses) is probably worth mentioning. Also as a side note, I know EOY means End of Year, so many acronyms, but that might not be the case for non-English speakers.

I saw this comment in one of Vitest's PR from @sheremet-va maintainer, dated 4 days ago

What's the timeline for v1?

This month.

Excited to know v5.0 and Vitest 1.0 are both coming real soon :)

Thanks for reviewing the PR and the suggestions @ghiscoding! Applied both to the blog post
