Offer git restore if urls were changed locally

[jan-vcapgemini]

As an IDEasy user, I want IDEasy to detect if I've modified my local urls repository.
It would be nice if IDEasy could provide a notification if urls is in an inconsistent state and offer an automatic git restore.

Currently IDEasy just checks if the urls folder exists and if not, it does a git checkout.
If the folder exists, IDEasy attempts only a git pull which can not detect any changes e.g. deletions.

If the user is offline and force mode is active, the user needs to be asked if he wants to repair (and lose) his local changes on the urls repository.

We can detect conflicts if not force is active for git update and in such case ask the user (with warning to lose all changes) if he wants to revert all his changes.

Can be closed because for urls we want to enforce a git reset.
Will be continued if other processes using git reset should wait for user input.
