Tutorial Page: index files setup and pipeline

Checkout those links to find a code example to a similar problem:

https://github.com/devonfw/architectures/blob/master/index.scss
https://github.com/devonfw/architectures/blob/master/index.js (main())

The '/tutorials' page need its own html tags and display logic.

index.js will:

• display the tutorials (redirect to tutorials)
• display searchbar
• display filter panel
• define the search engine
• define the filter engine

index.css holds the design of the html tags

This issue will focus on the display of each tutorial in a list and the search engine:
for now the searchbar will only search for the tags

Functions:
main(): Creates the divs for searchbar, filter panel, and the tutorials
renderTutorials(): renders the tutorial previews in tutorial divs
