[BUG] Deleting an Additional Application does not remove the entry from the database

[Seirade]

Describe the bug
When deleting an Additional Application, the entry remains in the additional_application table. The Launcher simply sets parentGameId to null, rather than deleting the record.

To Reproduce
For this example, I'm using the AddApp with id bed78efb-f203-45e4-a5f0-d87bd24fb46e

1. Open the DB and search for the AddApp:

select id, name, parentGameId from additional_app where id = "bed78efb-f203-45e4-a5f0-d87bd24fb46e";

2. Notice that the entry has a parentGameId of 000bf5cc-f047-53c1-711e-212af7cf76b9
3. Open Flashpoint and search for Castle Tales (or id:000bf5cc-f047-53c1-711e-212af7cf76b9)
4. Enable editing in Config if it already isn't, then click on the pencil icon to edit the entry.
5. Scroll down and delete the Additional Application (trash can icon) and confirm. Scroll back up and click on the checkbox icon to save changes.
6. Close Flashpoint, then open the DB and run the same query from Step 1
7. The parentGameId is now null

Expected behavior
The Launcher should delete the appropriate Additional Application from the table, rather than setting the parentGameId. Using the example above, it should run something like:

delete from additional_app where id = "bed78efb-f203-45e4-a5f0-d87bd24fb46e";

The function

launcher/src/renderer/components/RightBrowseSidebar.tsx

Line 927 in 87a5d03

 onAddAppDelete = (addAppId: string): void => { 

doesn't delete the add-app. Child curations PR will fix this.
