Invoking lazygit in a repository randomly prints the gpg card reader prompt (yubikeys and such)

**Describe the bug**
Running lazygit in any repository will randomly invoke gpg, which tries to ask for yubikey signing. This not only breaks the prompt but also then will timeout and the command log will show the git output. I believe this may be due to gpg.commitSign = true and gpg.tagSign = true, but I don't know why exactly its doing that.

**To Reproduce**
Steps to reproduce the behavior:

1. Run lazygit in any repository

**Expected behavior**
Do not randomly invoke signing, and especially do not break the prompt.
