After forking someone else's project, cloning it to your local machine, assuming the original repository author has added a new v5-dev branch, how do we synchronize this new branch?
Pull the new upstream branch into the local repository
git remote add upstream https://github.com/dromara/hutool.git
Fetch the new upstream branch
git fetch upstream
Create a new branch called v5-dev locally and switch to that branch
git checkout -b v5-dev upstream/v5-dev
Push the local v5-dev branch to your forked remote repository
git push origin v5-dev
