fix: fix types in apps/swagger (fixes #10023 and required for successful Railway build)

[stabildev]

(Reimplementation of #12681)

What does this PR do?

Fix some typing issues in apps/swagger that cause Railway build to fail.

Should also fix #10023

Notes

• Renamed snippets.ts to snippets.js as it doesn't contain the necessary types which leads to build errors on Railway. The types are not available.
• Removed two non-existing props from index.tsx See here for syntaxHighlight prop

Type of change

• Bug fix (non-breaking change which fixes an issue)
• Chore (refactoring code, technical debt, workflow improvements)

Mandatory Tasks

• Make sure you have self-reviewed the code. A decent size PR without self-review might be rejected.

Checklist

• I haven't added tests that prove my fix is effective or that my feature works
