PayPal Page Typo Edits

Issue Location: Main Title changed from Paypal to PayPal for typographical consistency. (Also change on left navbar.)
Issue Location: Text under Header "How to use service by paying through PayPal"

Proposed Text Updates:

1. Go to the Marketplace Portal. (Hyperlink to - - https://beta.singularitynet.io/)
2. Pay for a service through your PayPal account.
3. If you don't have a wallet, the application will create a wallet and a channel for you. The application will then deposit the equivalent AGI tokens in to the channel.
4. Now you can make a call. The DApp components hide all the complexity on making these calls.

For more details refer to Invoking a Service using Marketplace DApp. (Hyperlink to said page. - - https://dev.singularitynet.io/docs/ai-consumers/marketplace-service_invocation/ - - Possibly move this text above the diagram for easier access as well.)
