Preview / go to snapshot

[bakasmarius]

Clear and concise description of the problem

Our team migrated from Jest to Vitest in our NestJS backend project and we were very happy until we realized we were using a few features from snapshot-tools extension so often that we even forgot it was a separate VSCode extension 😅 (we are using almost 500 x .toMatchSnapshot() to validate data in the test files, so previewing snapshots in the same window where the test code is, is a very nice development experience)

There is a PR in that repo that should enable those features with Vitest, but the repo seems to be abandoned and I couldn't make that PR work locally on my VSCode.

So those features simply are these:

1. When hovering with the mouse over these functions: .toMatchSnapshot() and .toThrowErrorMatchingSnapshot() - we should see the actual snapshot that we are asserting inside the popup instead of info about these functions.
2. When using CTRL + Left Mouse Click on .toMatchSnapshot() and .toThrowErrorMatchingSnapshot(), it should go to a snapshot itself inside the snapshot file instead of going to the function definition.

So my questions are:

1. Would it be possible to add these features to Vitest extension?
2. Could they be optional, toggled in the settings?
3. Should it rather be a separate extension?
