Vue: Consider custom code snippet in story code panel

[larsrickert]

Follow up PR for #29253

What I did

• Update the story "Code" panel added in Docs: Add code snippet to addons panel #29253 to consider custom code snippets. Previously, stories with custom code snippets did not show any code snippet or reused the one from the previously opened story
• remove default "html" format which breaks react/JSX snippets/formatting
• updated the styles to remove unnecessary margin and made the code full panel height
• replace useAddonState with useState because the code snippets are individual per story so persisting the state globally does not make sense / is not needed
