Codemods: Enhance mdx-to-csf codemod

[valentinpalkovic]

Closes #26140, closes #26130, closes #26146

What I did

• I have fixed an issue where files were not renamed from .stories.mdx to .mdx although the transformation was successful
• I have fixed an issue where components doesn't exist in stories.mdx files but a .stories.js file was created
• The ArgsTable component doesn't exist anymore in Storybook 8.0. The codemod was adjusted to use <Controls /> instead.
