Run Yarn on root folder only

[Krlier]

Recently I came across a repository with more than one Yarn.lock file, one in the root directory of the project and another inside a folder, which caused some issues when running huskyCI.

I believe that in the future it would be nice if huskyCI could find all Yarn.lock files in a project and run an analysis on each and every one of them, which will be addressed in this issue.

For now, my proposal is that huskyCI searches only in the project's root directory for the Yarn.lock file.

Changes:

API:

• api/config.yaml: Add verification for Yarn.lock in the project's root directory only.

Hello, @Krlier! I got your point! Sounds fair enough to me. This is indeed something we should handle soon! Thanks for this contribution.
