[Feature]: support installing browsers as extras

[DetachHead]

🚀 Feature Request

python packages can define extras, which are additional optional parts of the package. more info here

it would be nice if playwright defined each browser as an optional extra, so that they can be installed like so:

pip install playwright[chromium,firefox]

Example

No response

Motivation

this prevents the user from having to manually run playwright install after installing all of their dependencies. in my project, we have an "install dependencies" script which basically just runs both poetry install and playwright install. it would be nice if we could just specify the browsers as extras in pyproject.toml so we don't need the additional script.

Great! So, if a browser isn't specified, do you propose that nothing changes? For example, if the user installs Playwright as pip install playwright, then they will still have to use the playwright install script.

yeah
