[No QA] Docs updates for E/A#93937 saved searches sorted alphabetically

[MelvinBot]

Explanation of Change

Expensify/App#93937 changed the Search sidebar so that Saved searches now display in alphabetical order by name (previously they appeared in creation/insertion order).

The help article Using Reports in New Expensify documents how to save and view saved searches but did not mention any ordering. This PR adds a one-line note in the How to save a search section so the documented behavior matches the product.

What changed

• docs/articles/new-expensify/reports-and-expenses/Using-Reports-in-New-Expensify.md: added "Saved searches are listed in alphabetical order by name." after the instructions for viewing saved searches.

Authoring compliance

• No new headings added; existing single-# / ## structure preserved.
• UI labels (Saved section, Type dropdown) left unchanged and already match the live UI.
• Change is scoped to the single existing workflow (saving/viewing searches).

Source PR

• Show saved searches in alphabetical order #93937 — Show saved searches in alphabetical order
