Tink CLI template update when used with "stdin" still requires "--path"

[ichekrygin]

Related to: #587

tink template update should not require --path argument when updating template data over stdin.

Expected Behaviour

vagrant@ubuntu-focal:/vagrant/compose$ cat ./manifests/template/ubuntu.yaml | tt update 6f18beff-89d2-11ec-b67d-0242ac120004
Updated Template:  6f18beff-89d2-11ec-b67d-0242ac120004

Current Behaviour

vagrant@ubuntu-focal:/vagrant/compose$ tt update 6f18beff-89d2-11ec-b67d-0242ac120004 < ./manifests/template/ubuntu.yaml
2022/02/09 18:16:46 Nothing is provided in the file path

Possible Solution

Current workaround:

vagrant@ubuntu-focal:/vagrant/compose$ cat ./manifests/template/ubuntu.yaml | tt update 6f18beff-89d2-11ec-b67d-0242ac120004 --path nothing
Updated Template:  6f18beff-89d2-11ec-b67d-0242ac120004
