docs: (IAC-1244) jmespath requirement not listed

[raphaelpoumarede]

I'm using the tool for a bare metal deployment using the ./oss-k8s.sh script (not the docker container) and I get the following failure because jmespath is not installed.

TASK [kubernetes/sas-iac-buildinfo : Create the sas-iac-buildinfo ConfigMap manifest file] *************************************************************
Friday 08 July 2022  07:27:35 +0000 (0:00:00.372)       0:00:00.982 ***********
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ansible.errors.AnsibleError: You need to install "jmespath" prior to running json_query filter
fatal: [localhost]: FAILED! => {"changed": false, "msg": "AnsibleError: You need to install \"jmespath\" prior to running json_query filter"}`

I see it is part of the requirements.txt file and installed when building the docker image, but it should be part of the documented requirements when not using the docker image.

Yeah that one is also tricky as it uses terraform so the login around adding in the iac-buildinfo into the cluster needs to be revisited. We'll look at adding the required list of tools here as well. Somewhat related to #12
