fix(hana-cloud-cap-add-authentication): close Step 4 JSON fence

[jung-thomas]

Problem

Fixes sap-tutorials/tutorials-ims#2721.

In hana-cloud-cap-add-authentication ("Add User Authentication to Your Application (SAP HANA Cloud)"), Step 4's Done button and the entire Step 5 are missing from the rendered tutorial. The progress bar shows 5 steps but only Steps 1–3 are usable.

Root cause

Step 4's xs-app.json fenced code block is a list-continuation fence indented 3 spaces under 1. Next open the xs-app.json file.... The opening fence ```json, every sibling top-level line, and the closing } are all at 3 spaces — but the block's opening brace { was indented only 2 spaces:

   ```json
  {                       <-- 2 spaces (wrong)
   "authenticationMethod": "route",
   ...

Under CommonMark / Hugo-Goldmark, a continuation line indented less than the opening fence falls outside the list-item content column. Goldmark therefore closes the code block immediately (emitting an empty <code class="language-json">), spills the JSON out as a plain prose paragraph (with the quotes smart-quoted), and reopens a second stray empty code block at the trailing ```. The resulting broken HTML structure collapses Step 4's Done button and swallows Step 5 in the browser.

Verified by rendering the before/after through the actual Hugo (extended, Goldmark) engine: the broken version yields an empty language-json block + stranded <p>{... prose; the one-character fix produces a single well-formed code block.

Fix

Indent the opening { from 2 → 3 spaces so it aligns with the fence and all sibling lines. One-line, content-only change.
