error on git pull

[hohwille]

When you create a local feature-branch of your settings and run devon ide setup you will end up in an error like this:

Installing devon autocompletion
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=origin/<branch> feature/fix-settings

Failed to run command: git pull -q

******** ATTENTION ********
ERROR: Failed to run command git
We are sorry for the inconvenience. Please check the above errors, resolve them and try again.
Exit code was 1

My observations are:

1. the end-user does not have a clue what git repo the error is about. Here it is the settings git repo but it could also be the mirrors or a project specific git repo. IMHO end-users will be confused.
2. this should only raise a warning but not an error preventing the setup to work. The intention should be that an ide admin can test the setup before pushing the new feature-branch with his changes.

Therefore IMHO doGitPullOrClone should be able to detect this scenario (no tracking for current branch) and log a warning instead of triggering a pull ending in an error.

Test of PR #773:
In case I am on a local branch:

There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details.

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=origin/<branch> local_test_branch

Can not update git repository: /d/projects/devonfw/settings
It seems you are working on a local branch. For testing, you may continue...
Do you want to ignore the problem and continue anyhow?
(yes/no):

In case I am offline:

And finally in case I have created a git repo without any remote:

Can not update git repository: /d/projects/devonfw/settings
This is a local git repo with no remote - if you did this for testing, you may continue...
Do you want to ignore the problem and continue anyhow?

For the record:

• If you want to do this for local testing and get annoyed by this yes/no question, you can simply add -f for "force" or -b for "batch" mode what will continue automatically entering "yes" for you.
• I improved doAskToContinue so the message is still printed and the answer is printed as Yes (batch/force) so from the logs one can better identify what was going on.

On GHA the change causes tests to fail:

Error: The operation was canceled.

So for some reason on github he fails to update mirrors git repo and for some yet unknown reason thinks he is on a local branch. He waits for user input what makes the build to fail/timeout.
