[Bug]: NGINX `envsubst` regression in `0.7.0`

[jrseliga]

Current Behavior (bug)

After upgrading to 0.7.0 the variables in the file passed --env-file option of services up are not replaced by the envsubst command

Expected Behavior (fix)

NGINX plugin envsubst respects --env-file

Additional context

Given

.env.devbox

NGINX_WEB_PORT=8004

nginx.template

# ..
server {
         # ..
         listen       $NGINX_WEB_PORT;
         # ..
}
# ..

Unexpected outcome on 0.7.0

DEVBOX_USE_VERSION=0.7.0 devbox services up --env-file .env.devbox

Results in (unexpected):

# ..
server {
         # ..
         listen       8081;
         # ..
}
# ..

Expected outcome on 0.6.0

DEVBOX_USE_VERSION=0.6.0 devbox services up --env-file .env.devbox

Results in (expected):

# ..
server {
         # ..
         listen       8004;
         # ..
}
# ..

Verified that I can repro on my machine. Looking into this now.

Adding the variable to the env section of the devbox.json works: the nginx.config is updated and uses the correct variable, so envsubst seems to be installing and working correctly.

It looks like the --env-file flag is maybe not getting passed to services
