feat(getSession): option to suppress server side getSession warning manually

[marcusklausen]

What kind of change does this PR introduce?

options param introduced on getSession with a suppressWarning prop to suppress the following server warning:

Using the user object as returned from supabase.auth.getSession() or from some supabase.auth.onAuthStateChange() events could be insecure! This value comes directly from the storage medium (usually cookies on the server) and many not be authentic. Use supabase.auth.getUser() instead which authenticates the data by contacting the Supabase Auth server.

What is the current behavior?

Currently the warning is displayed whenever getSession is accessed from the server, this causes excessive logs and hurts DX.
