Unable to render the environment variable set-up in [runners.docker]

Hi there!

From the pipeline job, I am trying to read environment variables which are configured as a runner level[runners.docker]. Upon reading the variable I am getting None. Env looks like the following -

[runners.docker] environment = ["ABC_HOST=https://jutsu.proxy.xyz.bm1", "DEF_HOST=https://jutsu.proxy.xyz.bm1"]

Any help will be appreciated. Thank you.
