refactor: rename String.bytes to String.toByteArray (#11343)
This PR renames `String.bytes` to `String.toByteArray`.

This is for two reasons: first, `toByteArray` is a better name, and
second, we have something else that wants to use the name `bytes`,
namely the function that returns in iterator over the string's bytes.
