Expected

Now that vitest-dev/vitest#7016 is merged, created ESLint configs shouldn't need to disable any no-unsafe-* rules in test files.

Actual

https://github.com/JoshuaKGoldberg/create-typescript-app/blob/94e253e7c5922dd2818e9cf7e3540ae43ba794e8/eslint.config.js#L91C32-L91C53

Additional Info

Looks like the upstream PR was reverted for the current major version in vitest-dev/vitest#8129:

The team decided to revert the change until the next major version.

Marking this as blocked until Vitest 8 4.
