Add --config, --help, and --version flags to edit-docs

- Implement --config (-c) flag to allow custom configuration file paths.
- Add --help (-h) flag to display tool usage and available options.
- Add --version (-v) flag to display the current Trilium version.
- Update electron-start.mts to correctly pass command-line arguments to Electron.
- Synchronize edit-docs version with the root package.json via update-version.ts.
- Resolve config paths relative to the configuration file's directory.

This makes edit-docs more robust and easier to use from external projects
and immutable environments like Nix.
