• I have read the contribution docs, and understand what's expected of me.

Link to the page on docs.getdbt.com requiring updates

https://github.com/dbt-labs/docs.getdbt.com/blob/6a1e40d949a04215a1a9a9eee927dc1967de5a38/website/docs/docs/dbt-versions/core-upgrade/08-upgrading-to-v1.7.md?plain=1#L69C41-L69C136

What part(s) of the page would you like to see updated?

The content under the subsection for dbt clean refers to the clean-paths in dbt-project.yml.
This requires correction because it is actually clean-targets and not clean-paths
The correction would involve changing clean-paths to clean-targets
