Sso required liminal auth with playwright

[nirmit-damania-dyno]

This PR adds the playwright package, used for authenticating your Benchling API connection with the user's credentials when SSO is optional or required on your tenant.

This flow will be used when internal_api_admin_email and internal_api_admin_password are not set or when SSO is set to required on your tenant.

When a liminal command is run and the above case is true, a playwright persistent browser window will open up to your Benchling tenant, and route the user to log into their SSO. After the user logs in, Liminal will be able to authenticate the Benching internal API connection. By default, playwright stores the user_data_dir in the root directory, so the user can setup a chrome profile as well and the next time they log in, the playwright browser can use the user_data_dir property to allow automatic re-login (depending on how the SSO is setup). This behavior can be turned off in the BenchlingConnection by setting playwright_data_dir to None.
