📚 Description

This PR fixes the linting warnings:

• overrides the vue/html-self-closing rule because there are a lot of self-closing tags in the playground
• adds a --max-warning=0 setting to eslint to ensure that the errors are not lost within the warnings
• removes unused props and sets the default values for props in the playground
• runs prettier --fix

Thanks!

Concerning

overrides the vue/html-self-closing rule because there are a lot of self-closing tags in the playground

Do you know what the "correct" way of handling (non-)self-closing tags are, such that also prettier and eslint are both happy?

Just saw that with these changes the "Custom components" in the showcase example are no longer rendered (in chromatic). See https://6631ee564bb0d0abcd38eb0f-exelvpgdgl.chromatic.com/?path=/story/features-custom-components--simple-component

I don't have the time right now to investigate this further.
