UpdaDocs: Added prerequisites (PS7+, EXO V3) and hybrid usage example…

Improved documentation in FreeBusyChecker.ps1 by clarifying prerequisites (PowerShell 7+, Exchange Online PowerShell V3 module) and adding a hybrid usage example for admins running OAuth checks in hybrid environments.

Issue:
The FreeBusyChecker.ps1 script header did not clearly state that PowerShell 7+ and the Exchange Online PowerShell V3 module are required to run successfully. Additionally, there was no example provided for hybrid administrators showing how to connect to Exchange Online before running the script with specific parameters. This lack of clarity could cause confusion or failed runs for admins who are new to the tool or working in hybrid environments.

Reason:
The change was made to improve clarity and usability of the FreeBusyChecker.ps1 script. By explicitly listing prerequisites (PowerShell 7+ and the Exchange Online PowerShell V3 module), administrators will know the required environment before running the script. Adding a hybrid usage example helps admins working in hybrid Exchange deployments understand the correct sequence of connecting to Exchange Online and running the script with parameters. These updates reduce confusion, prevent failed runs, and make the script more accessible to both new and experienced Exchange admins.

Fix:
Updated the FreeBusyChecker.ps1 script header to include a "Prerequisites" section that specifies PowerShell 7+ and the Exchange Online PowerShell V3 module as required. Added a hybrid usage example under the .EXAMPLE section to demonstrate the correct workflow for administrators in hybrid environments (connecting to Exchange Online with the EO prefix, then running the script with -Org ExchangeOnPremise -Auth OAuth). These changes improve clarity and usability without altering the script’s core functionality.

Validation:
The documentation changes were reviewed to ensure accuracy and alignment with the existing Quick Start guide and Exchange Online PowerShell V3 module requirements. The hybrid usage example was tested in a lab environment by first connecting to Exchange Online with the EO prefix and then running the script using -Org ExchangeOnPremise -Auth OAuth. The script executed successfully, confirming that the added example reflects the correct workflow. Since the update is documentation-only, no functional changes to the script logic were introduced.
