update storybook description for google crowler

[daniele-zurico]

We need to provide a description for search engines to display in the results listing, by adding the following to the manager-head.html file in your config directory:

<!-- .storybook/manager-head.html -->
<meta name="description" content="react agnostic library" key="desc" />

Please follow the below to create your branch

git checkout release/1.0.0
git pull
git checkout -b 'feature/documentation-crowler'
