Bug description

Attempting to utilize the slidesGrid property correctly in TS without errors, which is definitely console logging the correct data in my use case and working as it should. However, in the process of converting this project from JS to TS, I have been hit with this TS linter error: Property 'slidesGrid' does not exist on type 'Swiper'.

The codesandbox example I have created goes directly to the types source file in order to better illustrate the problem, but in my project I am simply importing the type from the library:

import type { Swiper as SwiperType } from 'swiper';

I am assuming adding the property to swiper-class.d.ts (or perhaps there is a more appropriate place for this particular prop) would resolve the issue, and if that is the case, I am happy to create a PR with that addition.

Thanks.

slidesGrid shows up as property of the Swiper interface
