chore(makefile) fix 'act' target with '--pull=false'

See https://github.com/nektos/act#using-local-runner-images

    > The --pull flag is set to true by default due to a breaking on older
    > default docker images. This would pull the docker image everytime act is
    > executed.

    > Set --pull to false if a local docker image is needed
