Message Box on git commit errors is too short

[KUGA2]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.74.2
• OS Version: Windows_NT x64 10.0.19044

Steps to Reproduce:

1. Create a git commit hook and print some lines in it (e.g. with pre-commit)
2. Commit a file via the gui "Commit" button
   
3. The commit hook fails.
4. An message box pops up:
   

This message box has 3 buttons which do work correct. However the text in there is not helpful.
It only shows the first line of the error. In my case this is pretty misleading. The issue is not unstaged files, it is some empty lines!
You can find the real issue with both the "Open Git Log" and the "Show Command Output" button. This is great.

I still think this should not print the first line only. I think it would be best like this:

Git commit failed!  <-- Window headline
-----
Log: 
<A reasonable amount of output lines, maybe 5>
...
-----
[Open Git Log] [Show Complete Command Output] [Cancel]

I got a less confusing example after i staged all modified files so pre-commit didn't output that warning.

As some pre-commit messages can be more than 5 lines, perhaps just put the command output in a scrollable text box.

This still happens and is confusing since it hides the real message.
