While editing Package Manifest via Inspector, the package technical Name can be set to an already existing Package's Name

Steps to reproduce:

1. Create a package
2. Click Manage -> Edit Manifest
3. Set the Package Name to "test"
4. Apply the Changes
5. Observe the Console window

Actual results: Package name is set to an already existing package's name, causing a package resolving error. Package that is causing the issue disappears from the Package List

Expected results: Data validation prevents using an already existing package name in the inspector. This safeguard already exists when using the Create Package option
