Bug: env test calls infoHandler instead of envHandler

[garg-dhruv]

https://github.com/stefanprodan/podinfo/blob/33dac1ba40f73555725fbf620bf3b4f6f1a5ad89/pkg/api/env_test.go#L18C34-L18C45

Here srv.infoHandler needs to be changed to srv.envHandler, to check the intended functionality.
This change results in test failure, therefore this test case needs to be updated.
