Create Plugin: Add error-handling for JSON parsing in utils

[leventebalogh]

What's the problem?

We received an error that happens when the return value of the go sdk version check command cannot be parsed as a JSON:

› npx @grafana/create-plugin@latest update
undefined:1

SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at file:///Users/l2d2/.npm/_npx/c8ca622b04c0c218/node_modules/@grafana/create-plugin/dist/utils/utils.goSdk.js:58:34
    at ChildProcess.exithandler (node:child_process:430:5)
    at ChildProcess.emit (node:events:514:28)
    at maybeClose (node:internal/child_process:1105:16)
    at Socket.<anonymous> (node:internal/child_process:457:11)
    at Socket.emit (node:events:514:28)
    at Pipe.<anonymous> (node:net:337:12)

What changed?

This PR adds a simple error handling for the JSON parsing, so it fails gracefully in case the return value is not a valid JSON.
