[No QA] Docs updates for E/A#88286 Update distance rate FAQ for auto-select on move

[MelvinBot]

Summary

• Updates the Distance Expenses FAQ to reflect the new auto-rate selection behavior when moving a distance expense to a different workspace (introduced in Auto-select valid distance rate when moving expense to workspace #88286).
• Previously the docs stated the expense keeps its original rate and shows a violation if invalid. Now it accurately describes that the system auto-selects the destination workspace's default rate and recalculates the amount.

Changed file

• docs/articles/new-expensify/reports-and-expenses/Distance-Expenses.md — Updated FAQ answer for "What happens if a Distance expense is moved to a different Workspace?"
