refactor: Remove branch specification from sal dependency

- Removed the branch specification from the `sal` dependency in
  `doctree/Cargo.toml` and `webbuilder/Cargo.toml`. This simplifies
  the dependency management and relies on the default branch of the
  repository.
- Updated `.gitignore` to ignore `sccache.log` to prevent it from
  being committed to the repository.
- Updated example commands in `example_commands.sh` to use a different
  collection name (`grid1` instead of `grid_documentation`) for testing
  purposes.  This avoids potential conflicts with pre-existing data.
- Improved code structure and organization in `doctree/src/lib.rs`.
