Same reason you use typescript. It helps you catch bugs and follow programming best practices. You also don’t need typescript, but with it your code is better. Typescript is technically just a really fancy linter. The actual compilation mainly just removes the type data and does some JavaScript engine compatibility.
I try and follow best practices always too, but when the linter is catching it for you it’s less to think about so you can focus on the important parts of the problem

Why do the typescript extensions to eslint exist then?
I don’t know. I never used eslint, therefore it is not needed. Everything works perfectly fine without it.
Why do you need it?

So why there are typescript extensions for eslint if both are linters for JS? You should either use eslint with JS or transpile TS to JS, right?
Are there bugs in TS that eslint can catch?
I personally never seen TS project with eslint.
Typescript compiler enforces language requirements, the linter enforces language best practices. Best practices help you avoid bugs.
Ok, I should check it out, then. Maybe I already follow all the best practices, so I wouldn’t need it anyway. ;)
