[mod] theme/simple: improve fmt/lint tech

This is one of various PR to refactor the simple theme internally.

Replace eslint tool with Biome. I have been using this for quite some time, and
it will help us to have more consistent and valid code without extending on
other third party plugins.

Removes unused dependencies.
