Support Jest 30

[tbouffard]

Is your feature request related to a problem? Please describe.

Currently, jest-playwright 4.0.0 declared jest 29 as peer dependency:

jest-playwright/package.json

Lines 53 to 58 in 3437dae

	"peerDependencies": {
	"jest": "^29.3.1",
	"jest-circus": "^29.3.1",
	"jest-environment-node": "^29.3.1",
	"jest-runner": "^29.3.1"
	},

This generates dependency conflict errors during npm install when I want to use Jest 30 in my project.

Describe the solution you'd like
Be able to use Jest 30 out of the box.

Describe alternatives you've considered

Current workaround when using npm to prevent dependency resolution errors:

• pass the --legacy-peer-deps option when running npm install
• add legacy-peer-deps=true to the .npmrc file

Add dev dependency: "jest-runner": "~30.0.0"

Additional context

Jest 30 doesn't introduce large breaking changes: https://jestjs.io/blog/2025/06/04/jest-30
It drops supports for Node 14, 16, 19, and 21. This may impact jest-playright@4.0.0 that still support Node 14+
