title: Add new commit to the existing Git tag
body: <p>I have created a Git tag as <code>v1.1</code> using </p>
  
  <pre><code>git tag -a v1.1 -m 'my version 1.1'
  </code></pre>
  
  <p>and I pushed that tag. Later, I made some changes related to <code>v1.1</code>. Now when I push new changes and check the git tag using 
  <code>git describe</code> it is showing me <code>v1.1-g2dcc97</code>.</p>
  
  <p>How can I add my new commit to the existing tag?</p>
