Remark slug and remark external links are deprecated

[MehakFatima24]

Closes #21838

What I did

I updated the dependencies of the project by replacing the deprecated remark-slug and remark-external-links with rehype-slug and rehype-external-links, respectively. This improves the codebase by using up-to-date and actively maintained packages.

@JReinhold @ndelangen I did something silly 🥲 and accidentally closed my old MR , I have updated this one and tested the sandbox for react-vite and ran the unit tests. Can you please review this?

[JReinhold]

Great work! A few minor comments, and then we need to upgrade @storybook/mdx2-csf when that gets released, which it should be soon.

[JReinhold]

I understand why you did this, we have a general discussion about the problem, but this is not that easily fixed, so you have to revert it.

(remember to run yarn install afterwards to update the lock file)

@MehakFatima24 your changes to @storybook/mdx2-csf have been released at v1.1.0, so you should be able to upgrade that dependency in this branch and finally see the changes work :) https://github.com/storybookjs/mdx2-csf/releases/tag/v1.1.0

@MehakFatima24 @JReinhold what's going on with this one? Any chance we can get it over the line sometime soon?

Hi @shilman , I'd be updating the dependency and testing the changes again today, so we can get this merged.

This has gone stale, and it's probably easier to redo it from scratch for anyone that wants this feature in. Closing.
