Discarding submodule changes while selecting parent folder does not work

[brandondong]

Describe the bug
At work, we have a submodule in a nested folder:

All this time, I thought lazygit did not support discarding submodule changes because I would open the tool, get to this screen, press d (Discard changes), hit confirm, and then nothing would happen.

Only today did I discover lazygit does actually support this. I just needed to move the selection down one item and then pressing d + confirm would work as expected.

The behavior is due to this check:

lazygit/pkg/gui/controllers/files_controller.go

Line 1071 in d11e11d

if firstNode.File != nil && firstNode.File.IsSubmodule(submodules) {

To Reproduce
Steps to reproduce the behavior:

git init
git submodule add https://github.com/jesseduffield/lazygit.git external/buildtools
git commit -m "add submodule"
git -C external/buildtools checkout HEAD~
lazygit

Press d and hit confirm.

Expected behavior
The submodule changes should be discarded. The folder only contains submodule changes so it should be no different than pressing discard on the submodule entry itself.

Also, I noticed range selecting both the folder and the submodule and then pressing discard would be disallowed due to

lazygit/pkg/gui/controllers/files_controller.go

Line 1058 in d11e11d

if submoduleCount > 0 && len(selectedNodes) > 1 {

I feel like this should also be allowed.
