Joshen Lim c4fe153fd8 Joshenlim/fe 4290 add save to notebook button in query tabs (#49667) ...

## Context

Adds a "Save" action for query tabs in the explorer, which opts for 2
options to either add to an existing notebook, or create a new notebook.
Both of these actions just opens the notebook in a new tab with unsaved
changes - the changes will only be persisted in the DB when the user
hits "Save" on the notebook.

For adding to an existing notebook, the snippet will be appended to the
bottom of the notebook - UI will scroll to the bottom after navigating
to the notebook.
