How to reproduce:
1. Create a GitHub account and go into github.com/settings/tokens
2. Press "Generate new token" and scroll down to the third row of the table
3. Check the "read:packages" setting ON
4. Scroll down and generate token
5. Place the attached "upmconfig.toml" file into the "Users/<username>" directory and rename it to ".upmconfig.toml"
6. Open the user attached project "PackageManagerDisplayNameReport.zip"
7. Open the Packages folder

Expected result: Packages use “displayName: Prefab Package Example ” from “package.json”
Actual result: Packages use “name: com.tsgcpp.unitygithubpackageexample.prefab” instead of “displayName: Prefab Package Example” from “package.json"

Reproducible: 2019.4.30f1, 2020.3.18f1, 2021.1.21f1, 2021.2.0b12, 2022.1.0a8

Note:
* The access token currently in the file ".upmconfig.toml" expires on 10/06, replace it with the token you generated if expired/doesn't work
* When renaming "upmconfig.toml" you might be warned that the file will be hidden, you can still open it with VScode if you go into the directory it's in
* For step 5 refer to the documentation: https://docs.unity3d.com/Manual/upm-config.html
* For result examples, please refer to the screenshots attached
