Drop clusters_applications_jupyter table

We're cleaning up the deprecated Clusters::Applications code related to Remove clusters_applications_* code (#366573 - closed)

Application code that used this table was removed in Clusters::Applications models removal (#388696 - closed)

In !117460 (merged) we dropped the foreign keys. This was in post deploy migration that has been run.

This MR's purpose is to

• drop the clusters_applications_jupyter table
• move the dictionary files per these instructions

For transparency, this was originally part of a single MR that drops many clusters_applications* tables, but sensing some concern around this I have split them into individual MRs.
