docs: Add documentation for Git module tests

- Added documentation for the Git module's test scripts, including
  test structure, running instructions, and details of each test.
- Added links to Git module tests in the main Rhai documentation.
- Improved overall structure and clarity of the Rhai documentation.

+# Git Module Tests
+
+This document describes the test scripts for the Git module in the SAL library. These tests verify the functionality of the Git module's repository management and Git operations.
+
+## Test Structure
+
+The tests are organized into two main scripts:
+
+1. **Basic Git Operations** (`01_git_basic.rhai`): Tests basic Git functionality like creating a GitTree, listing repositories, finding repositories, and cloning repositories.
+2. **Git Repository Operations** (`02_git_operations.rhai`): Tests Git operations like pull, reset, commit, and push.
+
+Additionally, there's a runner script (`run_all_tests.rhai`) that executes all tests and reports results. The runner script contains simplified versions of the individual tests to avoid dependency issues.
+
+## Running the Tests
+
+To run all tests, execute the following command from the project root:
+
+```bash
+herodo --path src/rhai_tests/git/run_all_tests.rhai
+```
+
+To run individual test scripts:
+
+```bash
+herodo --path src/rhai_tests/git/01_git_basic.rhai
+```
+
+## Test Details
+
+### Basic Git Operations Test
+
+The basic Git operations test (`01_git_basic.rhai`) verifies the following functions:
+
+- `git_tree_new`: Creating a GitTree
+- `list`: Listing repositories in a GitTree
+- `find`: Finding repositories matching a pattern
+- `get`: Getting or cloning a repository
+- `path`: Getting the path of a repository
+- `has_changes`: Checking if a repository has changes
+
+The test creates a temporary directory, performs operations on it, and then cleans up after itself.
+
+### Git Repository Operations Test
+
+The Git repository operations test (`02_git_operations.rhai`) verifies the following functions:
+
+- `pull`: Pulling changes from a remote repository
+- `reset`: Resetting local changes
+- `commit`: Committing changes (method existence only)
+- `push`: Pushing changes to a remote repository (method existence only)
+
+Note: The test does not actually commit or push changes to avoid modifying remote repositories. It only verifies that the methods exist and can be called.
+
+## Test Runner
+
+The test runner script (`run_all_tests.rhai`) provides a framework for executing all tests and reporting results. It:
+
+1. Contains simplified versions of each test
+2. Runs each test in a try/catch block to handle errors
+3. Catches and reports any errors
+4. Provides a summary of passed and failed tests
+
+## Adding New Tests
+
+To add a new test:
+
+1. Create a new Rhai script in the `src/rhai_tests/git` directory
+2. Add a new test section to the `run_all_tests.rhai` script
+3. Update this documentation to include information about the new test
+
+## Best Practices for Writing Tests
+
+When writing tests for the Git module:
+
+1. Always clean up temporary files and directories
+2. Use assertions to verify expected behavior
+3. Print clear messages about what's being tested
+4. Handle errors gracefully
+5. Make tests independent of each other
+6. Avoid tests that modify remote repositories
+7. Keep tests focused on specific functionality
