Add option to generate embedded form markup without styles

[wmnnd]

There should be a checkbox in the form generator for generating form markup without styles.

In a later iteration, this could be expanded to let users choose between the following options:

• no styles
• with tailwind styles
• with inline styles only

Hi! I’m interested in contributing to this issue.
If it’s still available and no one else is working on it, I’d be happy to take a look.
