Steps to reproduce:

1. Create a new Unity project
2. Open Package Manager window
3. Press “+” at the top left corner
4. Select “Create package”
5. Add a new package name and press “Create”
6. Verify that the "Inspector" window displays the package manifest
7. Click the "Edit" button in it
8. From the "Name" field, delete the entered package title
9. Observe the result

Actual results: Under the "Asset PostProcessors" section of the "Inspector" tab, an error message is displayed, which is not very informative: "Invalid Package Name '' ". The "Information" section does not indicate which fields are mandatory or optional, making it unclear which fields require input

Expected results: Mandatory fields should have "" next to them. That would help to understand which fields should be filled with data.

Reproducible with versions:* 6000.3.0a3

Not reproducible with versions: -

Can’t test with versions: 6000.3.0a2 as "Create package" functionality landed only in 6000.3.0a3

Tested on (OS): M1 Max - Sequoia 15.5
