[grotlue]

Some minor copy and UI improvements according to https://graylogdocumentation.atlassian.net/wiki/spaces/ECT/pages/3845685266/Mid-Cycle+Feedback

Setup Routing Step

• Setup Routing Step: Highlight the "Create Stream" button as the recommended option (e.g. swapping the column, adding a tooltip)
• Update the copy
• Update the copy of the pipelines connected to streams alert
• Add an extra button "Select Stream" which will show the stream select
• Rename next button text to "Skip & Start Input" when nothing is selected/created yet
  • When proceeding via "Skip & Start Input" the default stream will be used

New copy:

• Select a destination Stream to route messages from this input to.
• We recommend creating a new stream for each new input. This will help categorise your messages into a basic schema.
• Messages that are not routed to any Stream will be routed to the Default Stream.
• Pipeline rules can be automatically created and attached to the Default Stream by this Wizard.

New copy when stream is selected:

• Route messages from this input to an existing stream is selected.
• Pipeline Rules will be created when the Finish & Start Input button is pressed.
