[ios] Attempt to fix iOS workflow

Summary:
Seeing the following

error media/encryption-utils.js: Unexpected token: name (_000_000) in file media/encryption-utils.js at 17:27.

Looks like it's an issue with _ separators.

Tried removing to see if it resolves the issue.

Test Plan: Let's see what happens.
