Add an arrow icon for handling the UI of RTL

[jarvislin]

Fixes #18807

---

We have two arrow icons, → and ←. We only handle RTL for the ← icon, which causes the two arrows are in the same direction when the device is using the RTL language.

This PR contains a new arrow under the ldrtl directory for handling RTL.

To Test:

1. Install JP and sign in.
2. Click Reader at the bottom tab.
3. Find a post and click it.
4. Click the three dot icon at the top-right corner.
5. Click Visit site
6. Change the locale on your device to a RTL language, e.g. Arabic.
7. Back to the app.
8. The arrow icons should be displayed correctly.

Thank you for fixing this @jarvislin 🙇
The added resource looks good and the app behaved as expected when testing it on a Pixel 5 (Android 14) 🎉
