[PRO] EOL: update warming runtime to nodejs14.x #828

Prerequisites

• I am running the latest version. (up upgrade)
• I searched to see if the issue already exists.
• Are you an Up Pro subscriber?

Description

AWS started sending out mails about nodejs10.x reaching EOL. The warming runtime cannot be changed by up users. Please upgrade to nodejs14.x (no need to go for 12 I guess).
