Smarter branch deletion: Git alias 'del'

This Git alias "del" efficiently deletes a local branch while ensuring it's up-to-date with the main (or master) branch. It automatically switches to the main branch, fetches updates from the remote, pulls changes, and deletes the specified branch.

You may add this alias to your git config file located at /Users/your_username/.gitconfig

    git branch -D \"$@\"; \
