docs/recipes/auth/README.md
Feature request summary

i wan't set-cookie can be support by playwright
in docs/recipes/auth/README.md
i can only see that it support puppeter in the doc，when i use playwright， it throw a error:
/node_modules/lighthouse/core/gather/driver.js:82
const cdpSession = await this._page.target().createCDPSession();
^
TypeError: this._page.target is not a function

What is the motivation or use case for changing this?
first to be honest， in my department，suggest we use playwright to test our project
second the playwright project has 65.6 star，many project use it，it has many user

How is this beneficial to Lighthouse?
the playwright project has 65.6 star in GitHub，many project use it，it has many user，if it support， Lighthouse will have more user
