Add Get Support page to Data Streams docs

[j0sh-cl]

Summary

• Adds a new Get Support page at /data-streams/get-support directing users to submit a support ticket via app.chain.link/streams/billing
• Adds the Get Support nav item to the Data Streams sidebar, positioned after Sign Up for Data Streams
• Notes that the portal automatically attaches the user's streams user ID to the ticket
• Covers the case where credentials were issued outside the portal (user must include their UUID-format streams user ID manually)

Test plan

• Verify /data-streams/get-support renders correctly
• Verify nav item appears after Sign Up for Data Streams in the Data Streams sidebar
• Check links resolve (app.chain.link, app.chain.link/streams/billing)
