Add paging to "whiskey" page

[MikalDr]

The endpoint has been updated in regards to paging on the backend.

On the frontend we need to add a option to change page, and load new whiskey.

DoD:

• A call to the backend getting whiskey.
• Buttons (either a "load more" or a "1,2,3,...,n" system for loading pages
• Should be adaptable in regards to screen size

Acceptance Criteria:

• A button that can be pressed to load more whiskeys to display

getWhiskey(sortType: SortType, paging: Paging): [Whiskey]

paging {page, size}

[MikalDr]

This is impemented on the "grid-display" branch as infinite scrolling

@Veggissss when trying to query whiskey using paging, we get null.

line 58 in WhiskeyFetcher seems to fail. Please help 😄

Woops, workin on it

[Veggissss]

Should be fixed now in the latest commit.

The sorting input was changed to:

getWhiskeys(
    sort: {sortType: PRICE, reverse: true}
)

As stated in this PR
