Allow users using GPG to reword commits

[ghost-in-the-zsh]

Is your feature request related to a problem? Please describe.

I recently changed my repo's configuration to sign commits using GPG, but whenever I try to reword a commit, I get the following error message: Feature not available for users using GPG

Describe the solution you'd like

A solution that allows users to reword/rebase/etc while using GPG without running into this error. (See additional context.)

Describe alternatives you've considered

My current workaround is to exit lazygit and do things directly in the CLI. For example:

1. git stash
2. git rebase -i <sha1>^
3. Change pick to reword on the line with the correct <sha1>
4. Make changes in editor
5. git stash pop

Additional context

A screenshot of the error message from Lazygit is at the bottom. Lazygit version info:

$ lazygit --version
commit=91cb1ff29a01fdf643ccc38b97fd816b2a097bec, build date=2025-01-11T04:06:07Z, build source=binaryRelease, version=0.45.0, os=linux, arch=amd64, git version=2.45.2

There are use-cases that seem to work fine (e.g. reordering commits), so there may be other use-cases capable of producing this error that I just haven't come across.

Duplicate of #3758.

Short summary: if you are using a passphrase agent that allows you to sign without having to type a passphrase every time (e.g. gpg-agent), then you can enable this by adding

git:
  overrideGpg: true

to your lazygit config file.

If you aren't, you should invest into setting one up. 😄

I opened a PR to improve the error message.

I'll give that a try and see how it goes. Thank you.

That seems to have done the trick. Thanks again.
