--export is not supporting many documented output types, e.g. csv

[e-gineer]

Describe the bug

~ $ powerpipe query run --export csv "select * from net_certificate where domain = 'steampipe.io';"
Error: invalid export format: 'csv'

csv should be a supported export format?

help documentation says it is:

~ $ powerpipe query run
Error: accepts 1 arg(s), received 0
Usage:
  powerpipe query run [flags] [query]

Flags:
      --arg stringArray              Specify the value of a query argument
      --database string              Turbot Pipes workspace database (DEPRECATED: see https://powerpipe.io/docs/run#selecting-a-database for the new syntax)
      --export strings               Export output to file, supported formats: csv, html, json, md, nunit3, pps (snapshot), asff

Powerpipe version (powerpipe -v)
