New Tasks Scheduler - UI Eventing

## ACs
Add UI events to the new Tasks Scheduler UI

- Track when a user clicks on the Tasks documentation link (Learn More link underneath Create Task)
- Track when a user clicks the "Script Editor" link
- Track when the user clicks the "+ Create Script in Editor" option in the Select a Script dropdown
- Track when a user successfully creates their scheduled task via the "Schedule Task" button
- Track when a user fails to create their scheduled task via the "Schedule Task" button. If failed, track the failure reason code.
- Track when a user updates/edits a task using the invokable script task scheduler
- Track when a user updates/edits a task using the existing task scheduler
- Track when a user cancels task creation via the "Cancel" button
- Track when a user creates a task from an invokable script with parameters
- Track when a user clicks on the invokable script documentation link (Learn more link underneath the Param Values)

## Existing Task Events
- data_explorer_script_save_as_task
- valid_task_form_submitted

There are more existing events, consult @kristinarobinson for more information.

## Implementation
- New Tasks events will be sent to Rudderstack > Snowflake > Domo and filterable in the UI Events Domo Dashboard.
- Find some preliminary counts here: https://influxdata.domo.com/page/856789180. filters: Event = data_explorer_script_save_as_task and valid_task_form_submitted
- As of 10/24/22, most users use the dedicated tasks tab to create and save tasks, not the "save as" task option in the data explorer.
