🩹 [Patch]: Enhance error handling and summary reporting in documentation generation

[MariusStorhaug]

Description

This pull request enhances the error handling and reporting for PowerShell module documentation generation. Now, when documentation generation fails for one or more commands, the script collects detailed error information, summarizes the failures in a GitHub Actions step summary, and fails the build with a clear message.

Improvements to error handling and reporting:

• Introduced a $failedCommands collection to track commands that fail documentation generation, capturing their names and error details.
• After processing all commands, if any failures occurred, the script outputs a detailed summary to the console and to the $env:GITHUB_STEP_SUMMARY file, including a markdown table of failed commands and their errors, and then fails the build with an appropriate exit code.

Pull Request Overview

Enhances the PowerShell documentation build script to collect per-command failures, emit a structured GitHub Actions step summary, and fail the build when any command help generation fails.

• Adds aggregation of failed command metadata and detailed console/status output.
• Generates a markdown summary (including a table and overall success/failure counts) written to GITHUB_STEP_SUMMARY.
• Exits with non-zero status if any command documentation generation fails.
