(readme) Add guide how to set up AWS Rossum account in the terminal + SSO

[rehoumir]

Follow the instructions in this article to set up AWS CLI:

https://rossumai.atlassian.net/wiki/spaces/RAD/pages/2621112497/Logging+to+AWS

The only difference to the guide is to put this into ~/.aws/config:

[sso-session main]
sso_start_url = https://d-93670fe985.awsapps.com/start
sso_region = eu-west-1

[profile rossum-dev]
region = eu-west-1
sso_session = main
sso_account_id = 494114742120
sso_role_name = BedrockDev

Once you are logged into AWS via 'aws sso login --profile rossum-dev', everything should be ready

Now you should set up a PRD project:

cd ~/prd-projects # or whatever
prddoc init

Follow the instructions on the CLI and once done, move to the directory

cd
#Now download the source data from remote
prd2 pull
#now we execute the docomando
prddoc docommando

Now select the dir and subdir and queues by following the CLI instructions
