Fix full.md generation

The change is focusing on fixing the documentation generation problem in the Program.cs file. Previously, the code was appending version information to the wrong StringBuilder (indexContent), which didn't contribute to the actual content of the full change log. Now the correct StringBuilder (fullContent) is used ensuring that version-wise documentation is included correctly in the 'full.md' changelog.
