@copilot would you please check this PR? I'm aiming for friendly, easy to understand content for new users.

I've reviewed the content with new users in mind and made a few targeted improvements in commit 964aec2:

• Opening: Added a reassurance for users who are new to Camunda or BPMN ("don't worry — you don't need any background knowledge").
• What you'll learn: Added a note before the table that users don't need prior knowledge of these concepts.
• Prerequisites: Added brief context explaining why JDK is needed.
• Step 5 & 6: Clarified where the "Rocket" icon lives ("in the bottom toolbar") and made the Deploy button explicit in both deploy steps. Changed "Go back to" → "Switch back to" for consistent, natural flow.
• How it works: Added a note that users don't need to read or edit FEEL expressions to complete the guide — it's an optional reference.
• Complete!: Added a congratulations message to give new users a sense of achievement.

The overall structure and technical content are unchanged — these are tone and clarity improvements aimed at reducing friction for first-time users.
