#1108: Fix git authentication in terminal

[alfeilex]

Fixes: #1108

This PR fixes the issue with missing git authentication if no credentials are stored. The previous behavior was that the env variable GIT_TERMINAL_PROMPT=0 was set during each git command. This is removed within this PR since this was the reason for the missing git credentials prompt. Further, if run commands in --batch mode, GIT_TERMINAL_PROMPT=0 is set.

I tested the fix by creating native images for Windows and Linux. It is also notable that for git pull commands the credentials login prompt is not shown

Further I disabled GUI interaction when running git commands in Windows by setting specific environment variables.
