Android RTL Rendering Mathematical Symbols and Number Groups Backwards

运行必需的 Expo 54 reproducer，并将其 Android RTL 输出与 Expo 52 示例进行比较，重点关注 React Native 0.76.9 与 0.79.5/0.81.5 的差异。完成的标准是确定 Android 是否能够匹配之前对数学符号和数字分组的 LTR 处理，或提供有文档说明的 opt-out，而不要求为每个值添加 \u200E 字符。

Description

Since upgrading to Expo 53/54, we are seeing a big change in how numbers are rendered in Arabic mode (RTL) on Android.

Here are some examples of differences we're seeing (tested on both Expo 53 and Expo 54 using 0.79.5 and 0.81.5 respectively)
Expo 52 (RN 0.76.9): -123.456
Expo 53 (RN 0.79.5): 123.456-
Expo 54 (RN 0.81.5): 123.456-

Expo 52 (RN 0.76.9): +455.234
Expo 53 (RN 0.79.5): 455.234+
Expo 54 (RN 0.81.5): 455.234+

Expo 52 (RN 0.76.9): 12 - 13 = 25
Expo 53 (RN 0.79.5): 25 = 13 - 12
Expo 54 (RN 0.81.5): 25 = 13 - 12

I'm unable to find any documentation regarding this change which is not being applied on iOS (causing a lot of differences between the two devices). Please see the attached screenshots for more details.

Is there a way to opt out of this on Android and always render numbers with mathematical symbols in LTR mode?

The only way around it so far is to manually inject the LRT unicode character '\u200E' everywhere, but that's not a viable solution for our very large project.

Whilst I'm using Expo templates to help generate a minimal example, I do not believe this is an Expo specific issue.

Steps to reproduce

1. Install the minimal retro
2. Observe the difference in the numbers being rendered between React Native versions
