chore(web-components): cleanup drawer storybook

[davatron5000]

Previous Behavior

Found a visual regression for radio inputs on the Drawer component.

View issue: https://web-components.fluentui.dev/?path=/docs/components-drawer--drawer

New Behavior

• Updates the story to use the new RadioGroup syntax.
• Refactors all Drawer stories into a single story with more control options.

Questions

1. Rolling up the stories into a single story loses a bit of context, how much context do we need?
2. If we need more context, where should that live?

Note

This exposes a defect where you can't use labels to select a radioitem inside a drawer. Unclear if this is a problem with Drawer or with RadioGroup. I filed a separate issue for that: #31992
