Refactor: Reviewpad configuration

[ferreiratiago]

Description

This pull request introduces a refactor to the current reviewpad configuration file by taking advantage of groups.

It also solves the problem of reviewpad adding more than one size label when the pull request size keeps changing. For instance, a pull request that changes less than 100 lines will be labeled by Reviewpad with feat XS. However, if the total number of changed lines goes up 100 lines, Reviewpad will add the label label S but won't remove the previous feat XS label. The pull request will end up with the two labels feat XS and feat S.

How has this been tested?

The configuration was tested using Reviewpad playground.

• I have performed a self-review of my own code.
• I have commented my code, particularly in hard-to-understand areas.
