title: Git - How to change url/path of a submodule
body: <p>This is my <code>.gitmodules</code>:</p>
  
  <pre><code>[submodule "app/code/EthanYehuda/CronjobManager"]
          path = app/code/EthanYehuda/CronjobManager
          url = https://company@bitbucket.org/some_user/ethanyehuda_cronjobmanager.git
  </code></pre>
  
  <p>I need to change the url to <code>https://github.com/Ethan3600/magento2-CronjobManager.git</code></p>
  
  <p>So I just changed it:</p>
  
  <pre><code>[submodule "app/code/EthanYehuda/CronjobManager"]
          path = app/code/EthanYehuda/CronjobManager
          url = https://github.com/Ethan3600/magento2-CronjobManager.git
  </code></pre>
  
  <p>Then I added the file to the staging area and made a commit:</p>
  
  <pre><code>git add .gitmodules
  git commit -m "change url of submodule xy"
  </code></pre>
  
  <p>Then I executed <code>git submodule update --init</code>. But if I go to <code>app/code/EthanYehuda/CronjobManager</code> and show the remote, then I still get <code>https://company@bitbucket.org/some_user/ethanyehuda_cronjobmanager.git</code></p>
