Added end-point for linting a local repository as a .zip file

[RomitoVincenzo]

Using:

curl -X 'POST' \
  'http://127.0.0.1:8000/linters/repo-linter/' \
  -H 'accept: application/json' \
  -H 'Content-Type: multipart/form-data' \
  -F 'local_project=@Sentiment_Analysis_4SE_BERT-master.zip;type=application/x-zip-compressed' \
  -F 'bottom_size=4' 

Is now possible to request the linting of a local project as a .zip file, and, in this case of the Sentiment_Analysis_4SE_BERT to get the following response:
