[FEATURE] Next.js example setup

[mdjastrzebski]

Is your feature request related to a problem? Please describe.
Create an example setup for Next.js app. Similar to our current examples/web-vite there would be examples/web-nextjs folder which would showcase how to connect Reassure with Next.js

Describe the solution you'd like
Generate a basic Next.js app, prefereably in TS, but could be also in JS there are any serious problems with TS. Then add Jest, RNTL and Reassure deps, and Reassure scripts to it. In order to have something to measure add the [SlowList])(https://github.com/callstack/reassure/blob/main/examples/web-vite/src/SlowList.perf-test.tsx) component and tests (both unit and perf) from web-vite example.

Make sure that you can run Reassure locally and that it does not generate warnings about not being able to set performance flags.

Voila! That's it.

Potential issues
There could be problems with making jest run unit/perf tests in some cases (they were some for Create React App, but non fore Vite web app).
