## Description
This PR fixes issue of plugins not being seen on datasources page during
onboarding:
https://theappsmith.slack.com/archives/C05P3ME9MBR/p1703035861780029
**Root cause:**
The issue occurs because workspaceId is not present when we make an API
call to fetch all plugins. WorkspaceId comes from an API
`applications/new` and this API is called once we answer following
onboarding questions
Now If the API call gets completed before we select start with data
options, we get workspaceId and we are able to proceed ahead to fetch
plugins, but if this API call is not completed by the time we select
start with data, workspace id not available hence we dont see any
plugins.
**Solution:**
To make sure that we do not face such issue and we always workspace Id
available before we show 3 onboarding options, I have added a condition
of workspace Id for loading the component which shows 3 options, this
way 3 options will be shown only if workspace id is available, meaning
only if above API call is complete.
