Add more CSS frameworks to examples

[joshuadavidthomas]

Within the example directory, there are a handful of examples using popular CSS frameworks.

At the moment, these include:

• Tailwind CSS
• Bootstrap v4 and v5
• PicoCSS

The more examples the better! If there is a popular framework we are missing, we would love to have it included.

I would first comment here with the name of the framework, a link to either the repository or main website for the framework, and the example you would like to include.

The example should be open source, as we don't want to violate any license that may be attached.

For example, the Tailwind CSS example comes from one of the public templates offered in their Tailwind UI package, shown here. It gives a good example of how to use django-simple-nav within the context of the Tailwind UI templates, and if someone has a license to that product, they can then take it and apply it to one of the ones behind the paywall.
