fix: [AAP-46553] modify the project clone playbook for ansible-core 2.19 (#1321)

`omit` should always be the end state, and not used in the middle. 

https://issues.redhat.com/browse/AAP-46553

e.g
```
version: "{{ scm_branch | default(omit) | quote }}"
```
gets interpreted as 
```
"cmd": "/usr/bin/git checkout --force '<<Omit>>'",
```
