show env vars as export statements

[tarekrached]

rn you can view the env vars for a task def / run as json, but what would be really useful is to view them as a series of export statements, so you can paste them into a container shell. ie, if your env vars are

{
  "FOO": "BAR",
  "FOZ": "BAZ"
}

it would be awesome to be able to click a shell export button (like the current json button) and see and/or paste to clipboard the following:

export FOO='BAR'
export FOZ='BAZ'
