Lazygit hangs after branch checkout command due to interactive git hook

[med8bra]

Describe the bug
Lazygit hangs in checking out state when there is interactive post-checkout git hook

To Reproduce
Steps to reproduce the behavior:

1. Setup a git repository with an interactive post-checkout hook

echo 'exec </dev/tty && read line || true' > .git/hooks/post-checkout
chmod u+x .git/hook/post-checkout

2. Open lazygit, and go to 'Branches' pane
3. Checkout branch
4. Lazygit hangs in 'Checking out' the branch

Expected behavior
Lazygit shouldn't hang on checkout, possible behaviors:

1. provide user control to interact with the git hook stdin.
2. terminate the git hook once checkout is done.

Screenshots
Status 'Checking out' doesn't change

Version info:
Lazygit: commit=, build date=, build source=nix, version=0.41.0, os=darwin, arch=arm64, git version=2.44.0

Additional context

I saw how you handle credential requests sync.go#Pull, maybe it would make sense to give user access to stdin when a command is interactive as in edit command.

Just noticed this as well. We have a git hook that wants to request that a checklist is covered before pushing. The user is supposed to say "y" at tty when answering checklist items. We'd prefer to do it on the CLI rather than resort to adding the checklists as a Github extension.

exec < /dev/tty

while true; do
  read -p "[pre-push hook] Have you viewed the change or feature in-app before pushing? (Y/n) " yn
  if [ "$yn" = "" ]; then
    yn='Y'
  fi
  case $yn in
      [Yy] ) exit 0;; 
      [Nn] ) exit 1;;
      * ) echo "Please answer y or n for yes or no.";;
  esac
done
