feat: la liga teams endpoint

[GuilhermeFernandes01]

Hi @ageddesi! Relates to #159.

• Add la liga endpoint
• Create helper to get random subarray, which will be useful to many other routes
• Add tests to la liga endpoint
• Add jest coverage report (which I think is very useful)
• Add supertest types

PS: coverage report is not working for routes files by the way it is implemented.

@GuilhermeFernandes01 Seems to be a package.json conflict :P

HI @GuilhermeFernandes01 can you delete package-lock.json and node modules then re-run npm instal.

This should resolve the conflicts and then ready to pull add tag with that sexy hacktober-accepted :P

Hey @ageddesi sorry for the delay, merge problems fixed.
