yarn install / yarn test does not work out of the box for typescript exercises

[elmq0022]

node and yarn versions

two-fer$ node --version
v20.9.0
two-fer$ yarn --version
3.6.0

The instructions of yarn install and yarn test don't work out of the box. I imagine there is some mismatch on package versions.

This forum post seems to have a workable (albeit slightly annoying) work around, https://forum.exercism.org/t/issue-with-local-jest-type-definitions-yarn-3-and-jest/6867

Basically it's:

yarn install
npm i --save-dev @types/jest
yarn install
yarn test

Here's my install and the error for reference.
