This pull request includes updates to configuration files and PowerShell scripts to improve linting controls and documentation. The main changes are grouped into configuration improvements and documentation enhancements.

Configuration improvements:

• Added a new Linter section to .github/PSModule.yml to explicitly disable several validation checks in the CI environment, such as Biome format/lint, GitHub Actions Zizmor, JSCPD, and various Prettier validations.
• Updated .github/linters/.markdown-lint.yml to disable the MD024 rule (no duplicate headings allowed) and clarified the punctuation list for MD026, allowing for more flexibility in markdown documentation.

Documentation enhancements:

• Added a .DESCRIPTION section to the comment-based help in src/functions/private/Get-InternalPSModule.ps1 to provide more detailed documentation for the function.
• Added a .DESCRIPTION section to the comment-based help in src/functions/private/Set-InternalPSModule.ps1 for improved clarity and completeness of the function's documentation.
