As a user, I want a more informative “Insufficient funds for gas” warning on the send screen

### **Description**

On the send screen, the user is shown an "Insufficient funds for gas" warning, but no other information about gas. So the user doesn't know if they have insufficient funds because prices are currently high or because the gas limit of the particular contract interaction they are attempting is high.

### **Technical Details**

- Improve warning/error message shown to the user
- Implement a link in order to navigate the user where he can buy the required token

### **Acceptance Criteria**

- User should see a more detail description when he does not have funds for gas
- User should have a happy recovery path, directing them to purchase the native token
