set env-var for k-orc

pull korc envvar from dependencies

Shell check is flagging a valid warning here, if the name is missing (usually human error) we'll carry on using junk in the var

Could we pre-set these vars to NOT_SET before reading using jq, this also acts as a guard because if a user contacts us it's easy to see the NOT_SET and ask if they've changed their dependencies file

[DavidFair]

I think this will break as we're now setting them to NOT_SET overriding the original values read in line 28, unless I'm reading it wrong?

I think the NOT_SET needs to be before set_env_vars "dependencies.json", so if any are missing in from dependencies.json it will stay as NOT_SET

Retested on a VM, this is still working the the additional changes so LGTM
