696: Add all-args-constructor for easy initial config Pagination r=curquiza a=jonaskahn

# Pull Request for Enhancement

## What does this PR do?
This is a tiny PR to make the Pagination initial more easier.
The current implementation make extra lines to config Pagination. Here is an example:

**Before**
```Kotlin
val index = meilisearchClient.index(it.getIndex())
val defaultPagination = Pagination()
defaultPagination.maxTotalHits = 5000
index.updatePaginationSettings(defaultPagination)
```
**After**
```Kotlin
val index = meilisearchClient.index(it.getIndex())
index.updatePaginationSettings(Pagination(5000))
```
