Fix invoke example for Windows CMD

[edmuthiah]

Description of changes:

Currently the invoke example cargo lambda invoke rust-lambda --data-ascii '{ "command": "hi" }' does not work on Windows and returns the following error because of the way that Windows handles single quotes. Trying to invoke the command as shown in the readme returns: error: Found argument 'command:' which wasn't expected, or isn't valid in this context

This change the example invoke command to run for Windows, Mac and Linux.

This isn't a Windows-specific issue, but a shell-specific issue. More specifically, CMD. If we do go ahead with this change, however, please update the rest of the examples to follow this convention.

I recommend to keep them seperated, and show examples for both Linux/MacOS and Windows.

What is the benefit to doing this? Escaping the double quotes should work on most modern shells.

[bnusunny]

Linux and MacOs users could use a simpler format.

How can we do this without cluttering the docs?

[bnusunny]

Add one section to talk about it. There is an example in AWS CLI doc.

Done 👍🏽 Let me know if it's in an appropriate spot.

I suggest to put this note close to the first apperance of cargo lambda invoke.
