Resolves:

https://scratchfoundation.atlassian.net/browse/UEPR-429

Changes:

Deletes the tooltip popup logic and all code related to it in the project view page component

We'd also want to remove the logic related to the modal shown after the tooltip closes. See https://github.com/scratchfoundation/scratch-www/pull/9638/files for reference on the PR that introduced the feature callout.
