Pull Request

📖 Description

Solving several issues like stated in the issue #3345:

• Pages now are printed on a new page for each H2 (except the first H2) found.
• The videos page does not have video's in the printed version, but a link to each video.
• Hiding certain UI elements that are not relevant when printing a single page like the header, nav menu, footer and aside.
• Hiding interactive elements like buttons.
• Whenever a FluentTabs element is used, all the content for each tab will be placed below eachother, instead of only 1 tab showing in the printed version.

👩‍💻 Reviewer Notes

If you find any more issues on pages please let me know, it was really hard to go about each page and find elements that are not correctly printed yet, so i might have missed some!

📑 Test Plan

Run the Demo website locally and try to print the pages in multiple browsers. I have tried Chrome and Microsoft Edge.
