Update release.md to remove devops tasks and include local backup strategy

[philknows]

Motivation

Improve the RELEASE.md release manager checklist from lessons learned up to v1.1.0 release.

Description

This PR is to update the Release manager checklist to remove tasks specified for the PM + Devops. It only serves as a reminder, but not an action item for the release manager. Also includes a strategy of backing up local stable and unstable branches before merging incase of using the wrong merge strategy.
