[bug] pkl - allowedResources = null disallows reading env variables

[harlequin]

Describe the bug

The current version of rpkl disallows reading the environment variables.
Issue already raised and also resolved yesterday evening

z-jxy/rpkl#21
z-jxy/rpkl#22

Steps to reproduce

Somewhere in a *.pkl file

...
command = read("env:CI")
...

Problem solution would be to update the crate to 0.3.5 which includes the properties settings,
It is implemented that the default properties are fitting to the cli interface defaults from pkl, which is including the possibilities of reading env variables.
