[UX]: Add submission review note for test procedures

[joyalgeorgekj]

Added a note in local setup guide docs to link test related docs for fast onboarding and error/mistake free submittion from local setup.

This was mentioned in Exercism Forum and I took initiative to do the PR.

Received go ahead from @SleeplessByte.

Let me know if this needs improvement.

Thank you. I will ping @iHiD for this. It will take time for it to be reviewed as we normally do not accept PRs here but I think there is room for this to be accepted.
