Remove unnecessary Right-to-Left Mark (U+200F) from Arabic locale format L

📝 Description

This PR removes the Right-to-Left Mark characters (RLM, U+200F) from the Arabic (ar) locale’s L date format.

Reason

The L format currently contains RLM characters:

L: 'D[U+200F]/M[U+200F]/YYYY'

These characters are intended to adjust text direction, but:

Numbers and dates in Arabic are written left-to-right.

RLM is unnecessary for correct formatting.

When rendered in HTML or mixed-direction environments, these characters often cause dates to appear in the wrong order (e.g., year/month/day swapped or visually flipped).

The presence of hidden directional marks leads to inconsistent rendering across browsers and frameworks.

What this PR changes

Replaces the existing L format:

- L: 'D[U+200F]/M[U+200F]/YYYY',
+ L: 'D/M/YYYY',

No other locale settings are modified.

✅ Benefits

• Aligns the Arabic locale with real-world typographic rules.
• Prevents incorrect reordering of date components in browsers.
• Removes hidden characters that cause rendering issues in RTL/LTR mixed contexts.
• Makes the behavior consistent with other date libraries and expectations.
