Fix spo web get command and add ESM module instructions

[shahzdvp]

Fixes 'spo web get' command usage in documentation. Closes #5699

This pull request addresses the bug in the documentation where the 'spo web get' command was incorrectly using 'webUrl' instead of 'url' as a parameter. It also adds a note about using ESM modules when including CLI for Microsoft 365 as a dependency in Node.js projects.

Changes made:

1. Updated the example code to use 'url' instead of 'webUrl' in the 'spo web get' command.
2. Added a section explaining the need for ESM modules in projects using CLI for Microsoft 365.
3. Provided an example package.json configuration for a Node.js app using ESM modules.
4. Included instructions on how to set up and run a project with these configurations.

These changes improve the accuracy of the documentation and provide clearer guidance for developers integrating CLI for Microsoft 365 into their Node.js projects.
