Make stork script resilient to un-initialized git

[GiudGiud]

Problem

In the babbler folder created by using the command `./moose/scripts/stork.sh Babbler'.

I try to build a new application, it's still the same.

(moose) kimi@DESKTOP-7APSM1S:~/projects$ ./moose/scripts/stork.sh Abc
Initialized empty Git repository in /home/kimi/projects/abc/.git/

*** Please tell me who you are.

Run

  git config --global user.email "[email protected]"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

To store your changes on GitHub:
    1. Log in to your GitHub account
    2. Create a new repository named 'abc'
    3. In this terminal window, run the following commands:
         cd /home/kimi/projects/abc
         git remote add origin https://github.com/YourGitHubUserName/abc
         git commit -m "Initial code commit"
         git push -u origin main

To automatically enforce MOOSE C++ code style in your commits, run:

    cd /home/kimi/projects/abc
    ./scripts/install-format-hook.sh

To enable software quality assurance (SQA) documentation using MooseDocs, perform the
following steps after adding your git repository remote:

    1. Navigate to /home/kimi/projects/abc/doc
    2. Run './moosedocs.py init sqa --app 'Abc' --category abc'
    3. Commit the initial SQA changes using the following commands:
         git add /home/kimi/projects/abc/doc
         git commit -m "Initial SQA changes"
         git push origin main
    4. Add new SQA content to the forms in /home/kimi/projects/abc/doc/content/sqa

For general assistance in MOOSE-based application SQA, please contact the MOOSE
framework development team. For further info on the MooseDocs code documentation
system, please visit https://mooseframework.inl.gov.
