Hey @princerajpoot20

I've identified and fixed all the TypeScript any type issues in the codebase. I've replaced them with proper type definitions to improve type safety and developer experience.

Could you please assign this issue to me so I can create a PR? I'm ready to submit it once assigned.

Thanks! 🙏

@Sam-61s You can go ahead with this issue.
Also, are you sure we only have this in the places you mentioned and not anywhere else? Please cross-check it once, so that we don’t have to come back and fix it again.

Thanks @princerajpoot20 🙏

I've verified - all files mentioned in the issue are fixed (no any types remaining).

I also found some any types in other files (DocsNav.tsx, DocsMobileMenu.tsx, MDX.tsx, etc.), but those are outside this issue's scope.

Should I proceed with this PR for the mentioned files, or expand it to fix all any types? Ready to submit once you confirm! 🚀
