Step 2: ⌨️ Coding

• Modify fluere-plugin/src/downloader.rs ✓ da010ba Edit

Modify fluere-plugin/src/downloader.rs with contents:
• Import the `git2` crate at the top of the file.
• Replace the current implementation of the `download_plugin_from_github` function with a new implementation that uses the `git2` crate.
• Use the `git2::Repository::clone` function to clone the repository if it does not exist.
• If the repository does exist, use the `git2::Repository::open` function to open it, and then use the `git2::Repository::fetch` and `git2::Repository::pull` functions to update it.
• Handle any potential errors from the `git2` functions gracefully, returning an `Err` value with a descriptive message if any operation fails.

Modify fluere-plugin/src/util.rs with contents:
• Replace the `unwrap` call on line 25 with a `match` statement to handle the potential `Err` value.
• If the `create_dir_all` function returns an `Err`, return an `Err` value from the `home_cache_path` function with a descriptive message.
• If the `create_dir_all` function returns an `Ok`, continue with the current logic.
