fix: remove entitlement files editing for associated domains from config script

[saeedbashir]

We've added the capability to modify entitlements files on compile time for branch SDK to modify the associated domains depending on the values of the config under the scope of #283.

But modifying the entitlements file on compile time results in very odd issues like not maintaining user sessions across runs, not letting the user login sometimes, etc.

I've removed the entitlements modification part from the config process script. We will review it post MVP and will see whether we will be able to modify entitlements with the whitelabel or not.
