⚠️[Urgent] Broken Button Group links in list.mdx and roundness.mdx

[jsakamotoIGJP]

The Angular `list.mdx` and `roundness.mdx` topics both link to Button Group as `/components/inputs/button-group`, which 404s. The correct URL is `/inputs/button-group`.

• docs/angular/src/content/en/components/list.mdx
• docs/angular/src/content/en/components/themes/roundness.mdx

Also worth noting: `npm run check-relative-links:ci` does not catch this broken link.

This broken link is already live in production, so users are hitting it right now. Please treat this as urgent and fix it as soon as possible.

@jsakamotoIGJP , we have a CI verification on links which failed to catch this. We believe it's because with the rewritten docs we also want to gradually phase out the angular-specific source and eventually have all platform docs come from a single file. This is probably not playing well with the current CI script for link verification. @dobromirts will look into it and fix both the links and the verification so we can be safe going forward with our docs overhauling efforts.

@ChronosSF @dobromirts Thank you for taking care of this issue.

I confirmed in my local build that the Button Group links from both list and roundness are now fixed in PR #535. I will wait for the changes to be deployed to production.

I also wanted to share one observation.
When I checked out the dtsvetkov/update-check-relative-links branch and manually reverted the changes in list and roundness, I ran npm ci and then npm run check-relative-links:ci. In my test, the broken links were still not detected.
Just sharing this information in case it is helpful.

Correction to my previous comment. I made a mistake in my test. After checking again, I confirmed that npm run check-relative-links:ci works correctly.
Sorry for the confusion.
