Setup of the git repo

Hi,

When I setup a new org with DevOps center it would be great if It could create the github or bitbucket repo for me. So that I could start using it in a few clicks.

Currently, you need to download and create the repo manually which is reducing the ability for non developer user to use DevOps Center.

While trying to use devops center we ended up with a github action:

```
name: Salesforce Daily Diff

on:
schedule:
- cron: '0 0 */2 * *' # Runs at midnight every 2 days
push:
branches:
- master
workflow_dispatch:

permissions:
contents: write

jobs:
diff:
runs-on: ubuntu-latest

steps:
- name: Checkout Repository
uses: actions/checkout@v2

- name: Install Salesforce CLI
run: npm install @salesforce/cli --global

- name: Create Certificate File
run: |
path="dx.key"
if [ ! -f "$path" ]; then
echo "${{ secrets.SF_JWT_KEY }}" | tr '|' '\n' > "$path"
fi
echo "./$path"

- name: Hub Login
run: sf force auth jwt grant --client-id ${{ secrets.SF_CLIENT_ID }} --username ${{ secrets.SF_USERNAME }} --jwt-key-file ./dx.key --set-default --json

- name: Delete Certificate File
run: rm -f dx.key
- name: Set Date Variable
run: echo "CURRENT_DATE=$(date +'%Y-%m-%d')" >> $GITHUB_ENV

- name: Fetch Latest Code
run: git fetch origin

- name: Check Out Master Branch
run: git checkout master

- name: Retrieve All Metadata
run: sf project retrieve start --manifest manifest/package.xml

- name: Configure Git
run: |
git config --global user.name 'github-actions'
git config --global user.email 'github-actions@github.com'

- name: Check for Changes
id: changes
run: git diff --quiet || echo "has_changes=true" >> $GITHUB_ENV

- name: Exit if No Changes
if: env.has_changes != 'true'
run: echo "No changes detected. Exiting." && exit 0

- name: Stage All Changes
if: env.has_changes == 'true'
run: git add -A

- name: Commit and Push Changes
if: env.has_changes == 'true'
run: |
git commit -m "Daily Salesforce metadata update - ${{ env.CURRENT_DATE }}"
git push origin master
```

Thanks.
