chore(test): upgrade jest to v30

[webbugt]

Description

Basically update the function usage to work with jest 30.

The changes are rather trivial, used Copilot with official migration guide to scan the repo for incorrect function calls and fix them. Manually checked and validated all changes.

Motivation and Context

We needed this package in Jest 30 testing setup, downgrading was not an option
Fixes #371, although might break compatibility with older versions

How Has This Been Tested?

Tests in the repository are all passing and only modifications made we're the updated function calls

I don't see a reason to keep this instruction file in the repo since it has been used and will unlikely be used again.

[webbugt]

You're right, I will remove it
