Filter support for Leaderboard API

[Reterics]

Changed the leaderboard API to

• send the same type of response: {contributors:[], meta:{currentPage: number, totalPages: number, totalUsers: number,}}
• have less code duplications
• support all of the filters: minPoints, maxPoints, minPrs, page = 1, limit = 10, name

With this update the Issue 21 in the Frontend needs only minor changes, and will be easier to maintain.

minimum prs filter not working

[Reterics]

The original count: prNumbers implementation needed to be changed to counting the prs.

Since Prisma ORM doesn't support filtering directly by the aggregated count in the findMany function, I applied the filter and pagination after the findMany. I tested and it seems to be working.

Note: The code could be greatly simplified/speeded up if the prs number variable was added to webhook/github.js. (In this case the pagination could be put back intoPrisma, and the API call would be faster, but this is an another optimalization ticket)

agree, create a separate issue then.
