fix: redundant word in banner for Legacy stream documents (#7207)

* fix: Remove redundant "stream stream" output

fix: Change "Legacy stream" to "Legacy"

chore: Add "stream" to stream.desc as needed

Fixes: #6902

* chore: Remove unused stream_desc parameter

The stream_desc key isn't used in template/doc/docuemnt_draft.html to
don't pass it in nor compute it

Fixes: #6902

* fix: migrate the legacy StreamName
