Add support for `documentation` argument in pipeline.

[vkumbha]

As per the docs, pipeline supports documentation argument. But I get an error.

Argument	Type	Optional?	Description
documentation	String (Markdown)	Optional	A markdown string containing a long form description, used as documentation for the mod on hub.steampipe.io.

Error:

$ flowpipe pipeline list
Error: Failed to decode mod:
Unable to parse documentation attribute
(/Users/venu/turbie/turbot/_docs_qa/learn_flowpipe/learn.fp:4,3-42)

Here is my pipeline:

pipeline "get_astronauts" {
  title       = "Get Astronauts"
  description = "Get astronauts in space right now."
  documentation = file("./docs/index.md")

  param "url" {
    type    = string
    default = "http://api.open-notify.org/astros"
  }

  step "http" "whos_in_space" {
    url    = param.url
    method = "get"
  }

  output "people_in_space" {
    description = "List of people in space right now."
    value       = step.http.whos_in_space.response_body.people[*].name
    sensitive   = true
  }
}

Duplicate of https://github.com/turbot/pipe-fittings/issues/77, @vkumbha are you still seeing this with the latest version though?

Yes I'm fairly sure this has been fixed with the latest version. It's the same issue with https://github.com/turbot/pipe-fittings/issues/77
