When set `Diff Tool` and `Merge Tool` to DiffMerge, the APP will update `~/.gitconfig` with the following config:
[difftool "sourcetree"]
cmd = /Applications/DiffMerge.app/Contents/MacOS/DiffMerge/Contents/MacOS/DiffMerge --nosplash \"$LOCAL\" \"$REMOTE\"
path =
[mergetool "sourcetree"]
cmd = /Applications/DiffMerge.app/Contents/MacOS/DiffMerge/Contents/MacOS/DiffMerge --merge --result=\"$MERGED\" \"$LOCAL\" \"$BASE\" \"$REMOTE\"
But the correct path of DiffMerge is: `/Applications/DiffMerge.app/Contents/MacOS/DiffMerge`
Sourcetree: 4.1.5(241)
MacOS: 10.15.7
