When set via an environment variable an integer will be represented by a string, resulting in an error.
fixes: docker/compose#10667


The alternative would be to adjust the parsing of the yaml into the internal model, so it gets parsed as an int.
The env var is replaced in

newValue, err := opts.Substitute(value, template.Mapping(opts.LookupValue))

But it only allows setting strings and not int
Substitute func(string, template.Mapping) (string, error)

When set via an environment variable an integer will be represented by a string, resulting in an error.
fixes: docker/compose#10667
