Fixes #10325

Changes proposed in this Pull Request

The 60 day survey note is added when the store meets the criteria. With these code changes

• We stop adding the 60 day survey going forward.
• If the survey note is already added, we remove it.

I did not remove the code as we need to reference the note inorder to delete it e.g. WC_Payments_Notes_Qualitative_Feedback::possibly_delete_note();

Testing instructions

• Check a store that meets the criteria and has a note on develop
  
• Observe that with this branch, the note is removed.

• Run npm run changelog to add a changelog file, choose patch to leave it empty if the change is not significant. You can add multiple changelog files in one PR by running this command a few times.
• Covered with tests (or have a good reason not to test in description ☝️)
• Tested on mobile (or does not apply)

Post merge

• Link to testing instructions from release testing doc following these instructions : Add link here / 'QA Testing Not Applicable'
• Add or update critical flows and testing instructions for critical flows, if applicable.
• Add what's changed (description, screenshot, demo videos etc.) to the release announcement post, if applicable.
