♻️ Update and sync vimrc with alrra's + add set mouse=a

This commit improves readability and ease of use for the vimrc settings file, mainly through reordering, adding descriptive comments, and integrating the MinPac package manager. Notable changes include:

- Replaced Vundle with MinPac for package management, providing lighter and faster operation.
- Added custom commands for managing plugins with MinPac.
- Used "set" before each setting for consistency and readability.
- Added separators between different setting sections for easier navigation.
- Explained 'what' each setting does and moved complex explanations into comments.
- Updated the Emmet trigger key and the plugins list.
- Changed the plugin initialization process to be more robust and handle errors silently.
- Fixed inconsistencies in indentation and comment starts.
- Changed key mappings to use the comma as leader key for easier reach.
- Included webapi-vim plugin and JavaScript syntastic checker.
- Set spell checking language en_us.
- Enhanced the color scheme settings for Terminal mode.

The update is primarily aimed at simplifying Vim's initial setup process, improving navigation within the vimrc file, and ensuring a more user-friendly experience.
