test: add @vite-ignore to silence warning

[hi-ogawa]

Description

• related fix(vitest): print warnings form Vite plugins #6724

I just noticed Vitest emits import analysis warning after the change #6724. For now I added a bunch of @vite-ignore for our tests.

Alternatively, we can probably silence this by default since adding @vite-ignore might not be an option for existing users when it's coming from inlined dependency. I made a PR for this approach #6785.

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• It's really useful if your PR references an issue where it is discussed ahead of time. If the feature is substantial or introduces breaking changes without a discussion, PR might be closed.
• Ideally, include a test that fails without this PR but passes with it.
• Please, don't make changes to pnpm-lock.yaml unless you introduce a new test example.

Tests

• Run the tests with pnpm test:ci.

Documentation

• If you introduce new functionality, document it. You can run documentation with pnpm run docs command.

Changesets

• Changes in changelog are generated from PR name. Please, make sure that it explains your changes in an understandable manner. Please, prefix changeset messages with feat:, fix:, perf:, docs:, or chore:.
