Update examples with input JSON files for ledger tool

[ERoydev]

What

• I have added the input JSON files for the examples.
• I have added test cases in every example that show how our npm package approach is used.
• This is just a proposal because:
  • I have tried to avoid the npm package approach, but it's not possible to invoke instructions from our VS Code extension.
  • I cannot call vscode.command from a Node test (the Anchor ts-mocha tests) because Node doesn’t provide the VS Code extension host environment.
  • Its not good approach either to make user to copy paste the code locally.
  • The npm package looks more appropriate

Note

• All these JSON examples are generated using this npm package.
• In Anchor tests, we can generate the instruction data using Anchor commands, which handle all the Borsh serialization.
  This ensures there will be no mistakes.
• This approach of automatic input generation works only for Anchor projects.

Overall

• I think this approach is fine since i have tested in on anchor-example where we have different PDA code logic and it works without any errors (even the agave-ledger-tool Violation ones).
• I still should try to test it on even more complicated code.
