This allows you to enter your passphrase once for the session without needing to enter your passphrase potentially many times for each git command. The VS Code documentation is well written for setting up this SSH Agent on a variety of platforms, see [Visual Studio Code Remote Development Troubleshooting Tips and Tricks](https://code.visualstudio.com/docs/remote/troubleshooting#_setting-up-the-ssh-agent).
