Ensure that we bump dependencies at a predictable schedule

[mflendrich]

Dependencies (not just go modules, but also - perhaps primarily - the monitoring stack) should be upgraded to their new versions on a predictable schedule.

Proposal: create a "2 Week Before Release" section in the release notes and include a checklist to:

• bump go.mod
• bump the monitoring stack
• bump Scylla and Manager to the new versions
• (expand the list with anything else that makes sense)

I propose "2 weeks" to create enough buffer in case of releases with more time pressure.

The Scylla Operator project currently lacks enough contributors to adequately respond to all issues.

This bot triages un-triaged issues according to the following rules:

• After 30d of inactivity, lifecycle/stale is applied
• After 30d of inactivity since lifecycle/stale was applied, lifecycle/rotten is applied
• After 30d of inactivity since lifecycle/rotten was applied, the issue is closed

You can:

• Mark this issue as fresh with /remove-lifecycle stale
• Close this issue with /close
• Offer to help out
