More efficient mcp.json + fixed typos and trailing spaces

[DavidIsrawi]

Purpose

The mcp.json template found in the course calls for the Windows Command Prompt to run a node script within it. There are two challenges with this approach:

• cmd is specific to Windows
• the mcp.json format already supports node, hence the cmd portion is redundant as we can run the node script directly

As I was doing this change, I noticed some typos in the repo, so I went ahead and addressed the ones I noticed 🙂

Does this introduce a breaking change?

When developers merge from main and run the server, azd up, or azd deploy, will this produce an error?
If you're not sure, try it out on an old environment.
