Update README header

[sin4ch]

I want the header to be Personal Banking MCP or Mono Personal Banking MCP

I think the former is better, then the description will indicate that the MCP is powered by the Mono API?

I'm not sure if I should just market this as a Mono MCP or a personal banking MCP.

Sigh...

Hi @sin4ch
I think marketing this as Personal Banking MCP will be much better.
Better put Personal Banking MCP built using Mono API
