Update OwlCarousel2 typings

I updated the options according to https://owlcarousel2.github.io/OwlCarousel2/docs/api-options.html.

- added `lazyLoadEager` and removed `lazyContent` ([source](https://github.com/OwlCarousel2/OwlCarousel2/commit/44571f95d5850d19d27fa634d443d9215eae7699#diff-16d5a8e7f1181df10837309167888eed))
- renamed `dotData` to `dotsData` ([source](https://github.com/OwlCarousel2/OwlCarousel2/commit/1915cb0d415005f0df118919d1e433221e36a764#diff-16d5a8e7f1181df10837309167888eed))
- added checkVisible ([source](https://github.com/OwlCarousel2/OwlCarousel2/commit/e5ea9a506994c18ea2b0575df20bc6dfeb79feb0#diff-16d5a8e7f1181df10837309167888eed))
- added `slideTransition` ([source](https://github.com/OwlCarousel2/OwlCarousel2/commit/40e28e09e44dfee4cf6d9c5e31bf29770ea0ec20#diff-16d5a8e7f1181df10837309167888eed))
