cmd/dist: add doc file to fix go doc dist
$ go tool -h says:
For more about each tool command, see 'go tool command -h'.
but it was suggested to change the suggestion to say:
see 'go doc command'
In #18313.
That would work for every tool except dist, which has no doc.go.
This change adds a doc.go file to cmd/dist.
Updates #18313
