Support for Vitest v1.x

Wallaby now supports vitest@v1.0.x, a major update that was just released yesterday. We had been closely monitoring the progress of Vitest’s 1.0.x beta releases to ensure we could support the official 1.0.x version as soon as possible after it was released. There were numerous breaking changes and enhancements introduced in Vitest’s latest version that required updates to Wallaby’s integration. If you are using an earlier version of Vitest, we recommend reading the Vitest migration guide to understand changes that may affect your project.
