fix: 🐛 Correct encoding and file path references in examples

* Fixed encoding from `IDENTITY_H` to `IdentityH` in `Example01_Simple.ps1`.
* Updated file path in `Example01_Simple3.ps1` to use `$PSScriptRoot` for consistency.
* Removed commented import statement in `Example01_WithSectionsMix.ps1` for clarity.
* Added `.pdf` files to `.gitignore` to prevent accidental commits.
