🩹 [Patch]: Improve debug and null/blank values on the GitHub Actions output commands (#250)

## Description

This pull request improves the debugging capabilities and handling of
null or empty values in various functions related to GitHub Action
outputs.

Enhancements to debugging and handling of null or empty values:

*
[`src/functions/private/Commands/ConvertFrom-GitHubOutput.ps1`](diffhunk://#diff-932d91e541fddb09fdf24c5538bc3bff2f26aab6f4da41cb937c5a0b4bd53f99L58-R93):
Added multiple `Write-Debug` statements to provide detailed logging of
the process flow and improved handling of null or empty `$InputData` and
values.

Added `Write-Debug` statements to log the input object type and value,
and the processing of properties, including conversion to JSON with
increased depth.

Modified to read the file content as raw and added logic to handle empty
lines, along with additional debug logging.
