Unable to interpolate string

[tamipangadil]

Hi,

I have a simple build workflow file that contains some extra variables that can be found in env and runner such as runner.os and env.cache-name. But all of them are showing this error:

ERRO[0099] Unable to interpolate string '${{ runner.os }}-node-${{ env.cache-name }}-

I believe that you might also support having these values declared somewhere as either environment or command parameters but I don't see it in the current command help notes.

-b, --bind                   bind working directory to container, rather than copy
-C, --directory string       working directory (default ".")
-n, --dryrun                 dryrun mode
-e, --eventpath string       path to event JSON file
-h, --help                   help for act
-j, --job string             run job
-l, --list                   list workflows
-P, --platform stringArray   custom image to use per platform (e.g. -P ubuntu-18.04=nektos/act-environments-ubuntu:18.04)
-p, --pull                   pull docker image(s) if already present
-q, --quiet                  disable logging of output from steps
-r, --reuse                  reuse action containers to maintain state
-s, --secret stringArray     secret to make available to actions with optional value (e.g. -s mysecret=foo or -s mysecret)
-v, --verbose                verbose output
    --version                version for act
-w, --watch                  watch the contents of the local repo and run when files change
-W, --workflows string       path to workflow files (default "./.github/workflows/")

Are you planning to support this feature? Thanks!
