chore: add ci for rewrite project (#9)

* chore: disable mdlint (#6)

* resolve lint issues

Some issues where detected by the CI once run:
* use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo)
* File is not properly formatted (goimports)
* Magic number: 12, in <condition> detected (mnd)
* error-format: fmt.Errorf can be replaced with errors.New (perfsprint)
