🚨 User Impact 🚨

Are there any breaking changes? What is the end result perceived by the user?

For connector PRs, use this section to explain which type of semantic versioning bump occurs as a result of the changes. Refer to our Semantic Versioning for Connectors guidelines for more information. Breaking changes to connectors must be documented by an Airbyte engineer (PR author, or reviewer for community PRs) by using the Breaking Change Release Playbook.

If there are breaking changes, please merge this PR with the 🚨🚨 emoji so changelog authors can further highlight this if needed.

@erica-airbyte @johnlafleur updating the troubleshooting page in our docs page. Let me know what do you think about.

I'm removing some sub-pages which weren't updated at all and (I checked in Google Analytics) low traffic.
