In Release-Checklist, "Merge release notes" step is after Run release script step.

Proposal to change the merge step to run during release script.

Reasons:

1. Blog post PR may edit changelogs, if we do "clean" step after it is merged, there will be no conflicts.
2. There is a "bumpPrettier" step, there is a small chance that the blog post markdown file will need to be reformatted after it, bumpPrettier may also reformat changelog entries, there will still be conflicts.

Changes:

Change current steps from

• updateDependentsCount
• bumpPrettier
• cleanChangelog
• postPublishSteps

To

• updateDependentsCount
• cleanChangelog (In this step, add waitForEnter to wait for publisher to merge release note, can be a separate step before cleanChangelog)
• bumpPrettier
• postPublishSteps
