Docs: Preselect Framework / HTML [Doku]

[d-koppenhagen]

Currently when exploring the docs, you have always to remember to check out specific framework-related pages or switch the tab for code-examples.
It would be a big improvement when I could select my framework globally (may be handled like the version switch and/or query parameter). Then I would expect when checking out the code examples that the tab for the specific framework is preselected.

Also the "How to use" pages could be separated into tabs since the main use case is that I want to explore the docs for just one specific framework I think.
