## Overview

This PR is responsible for adding the `plugin:vitest/recommended` to the
extends array in the `.eslintrc.cjs` file.

This PR also updates a few of the tests because once the
`plugin:vitest/recommended` was added, some of the tests failed the lint
checks.

For the following files, I replaced the `toEqual ` methods with the
`toBe` methods per the vitest recommendations

- src/bin/index.test.ts
- src/shared/doesRepositoryExist.test.ts
- src/shared/runOrRestore.test.ts
- src/steps/writing/creation/dotGitHub/createWorkflowFile.test.ts

For the following files, I replaced the `toBe(undefined)` with
`toBeUndefined()` per the vitest recommendations

- src/shared/options/readGitAndNpmDefaults/readTitleFromReadme.test.ts
- src/shared/tryCatchLazyValueAsync.test.ts
