formatting of file naming card

These 2 exenstions in VS code actually help tremendously with formatting cards:

• https://marketplace.visualstudio.com/items?itemName=yzhang.markdown-all-in-one

The howto-cards have been deployed successfully: https://laurent.heirendt.pages.uni.lu/howto-cards/formatting-fn

And thanks for the tip!
