Configure sharding for Studio e2e tests (#43211)

## Problem

The e2e test suite for Studio takes around 20min. Feedback loop is too
long

## Solution

Try enabling [playwright
sharding](https://playwright.dev/docs/test-sharding#merge-reports-cli).
Only 2 shards for now

## Results

## Next steps

In future dedicated PRs, improve the tests themselves.
