Upgrade ts-jest

The version of ts-jest we were using was given a warning that it did not support TypeScript 5, even though it was working fine. The latest version of ts-jest adds official support for TypeScript and removes the warning.

We seem to be missing the package.json change.

There's no need to change the package.json in this case since we're only updating a minor/patch version. This is basically just running npm upgrade ts-jest so we get the latest version.
