Update 1.21 toggle is still in the experiments section

What happened?

I was checking on the new world screen, and my previously reported bug (MCPE-179719) has been fixed. The main point is the experiments section. As 1.21 beta is out, the experiment toggle isn't gone yet.

Steps to reproduce

1. Open world creation screen
2. Click experiments
3. The 1.21 experiment is still visible

Expected result

After the update, this toggle shouldn't be visible

Observed result

The toggle is visible

Additional info

• I'm not entirely sure if this is a bug or not, but it's a 1.21.0.20 beta.
