Follow-up: Update save value stream button text

Solution

We should update some of the VSA button text:

• "Save Value Stream" => "Save value stream"
• "Create Value Stream" => "Create value stream"
• "Edit Value Stream" => "Edit value stream"

Background

The following discussion from !61461 (merged) should be addressed:

• @msedlakjakubowski started a discussion:

  • Start with the action ("To do X, do Y")
  • Remove another image

  1. To undo any modifications, select **Restore value stream defaults**.
  1. Select **Save Value Stream**.

  Sidenote: if Save Value Stream is the text on the button, it should be capitalized as Save value stream, but it's a task for another time.
