gpg-agent not automatically starting on fresh process

### Search existing issues

- [x] I have searched the issue tracker and confirmed that I was unable to find existing issues for the problem I am experiencing.

### The problem

IF the user requires gpg signing to commit, they may come across this error when using a fresh GitHub Desktop process with no gpg-agent running beforehand.


### Release version

Version 2.9.12 (x64)

### Operating system

Windows 11

### Steps to reproduce the behavior

1. Start a fresh GitHub Desktop process and ensure any gpg-agent/gpg software isn't running in the background by using a task manager.
2. Try to commit changes.
3. Wait for a few seconds.
4. Error.

### Screenshots

_No response_

### Additional context

Shortly after the commit without a gpg-agent running and the user receiving this error, the gpg-agent process seems to start. While trying to reproduce this error, the commit 'throbber' in the blue bar seems to spin for a lot longer than it normally would.
