Test-DbaKerberos - Update documentation and examples, release from pipeline earlier

[potatoqualitee]

This pull request updates the Test-DbaKerberos PowerShell function to improve its documentation, clarify its parameter usage, and refactor how check results are handled internally. The main changes include more detailed and accurate descriptions in the function's help section, updated usage examples, the removal of the -Detailed parameter, and a refactor to return check results directly instead of accumulating them in an array.

Documentation and Usability Improvements:

• Enhanced the .SYNOPSIS and .DESCRIPTION sections to accurately describe the number and categories of checks performed, clarify the output structure, and specify behavior when using -ComputerName versus -SqlInstance.
• Updated the .EXAMPLE section to show more realistic usage scenarios, including credential handling and output filtering, and added new examples for result formatting and filtering by category.

Parameter and Output Changes:

• Removed the -Detailed parameter, simplifying the parameter list and focusing on structured output rather than verbose diagnostics.
• Clarified the purpose of the -Credential parameter and its role in Active Directory and WinRM connections. [1] [2]

Code Structure and Result Handling:

• Refactored the function to output each check result as a [PSCustomObject] directly, rather than adding it to an internal array, streamlining the output and improving pipeline compatibility. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

These updates make the function easier to use, provide clearer guidance to users, and improve the integration of results into PowerShell pipelines.
