can't import git url with package manager.

[allaze-eroler]

as the title suggest, i wasn't able to import it with a git cli or git url, all i need to do is download, unzip, and install it manually...

decided to add some more detail about this problem:

[Package Manager Window] Cannot perform upm operation: Unable to add package [https://github.com/Unity-Technologies/2d-renderer-samples.git]:
[https://github.com/Unity-Technologies/2d-renderer-samples.git] does not point to a valid package. No package manifest was found. [NotFound].
UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()

and

[Package Manager Window] Error adding package: https://github.com/Unity-Technologies/2d-renderer-samples.git.
UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()

i hope it will help you figuring what is the problem.
