Missing browser info message is not right

[DanielHabenicht]

When installed (without installing the browsers) the following can happen:

> playwright-cli open http://localhost:3000/
Browser "chromium" is not installed. Run `playwright-cli install-browser chromium` to install
> playwright-cli install-browser chromium
Browser "chromium" is not installed. Run `playwright-cli install-browser chromium` to install

The command that should be displayed is probably: playwright-cli install
