docs: Added user search details for developers/users

[PredictiveManish]

This PR adding a "markdown page for direct User search" for people who wants to find out how they can search any user of daily.dev and can see what are the benefits of this feature and can make their connection circle more larger than before.

I hope my branch naming will not be a problem? Please help review this, thank you 😁.
