I just updated jest to v30.0.5 and @emotion/jest seems to be working just fine. We should update its peer dependencies, since it is creating the following warning:

@types/jest is listed by your project with version 30.0.0, which doesn't satisfy what @emotion/jest (p7c3c4) requests (^26.0.14 || ^27.0.0 || ^28.0.0 || ^29.0.0)

Which in my case turns into an error (since we have configured yarn to be strict with peer dependencies).

I can open a PR for this.

Cheers.
