fj-app can crash because wgpu doesn't fall back PresentMode to Fifo anymore

wgpu doesn't fall back PresentMode to Fifo after gfx-rs/wgpu/pull/2803 .
This can causes fj-app crash.

On my MacBook Pro (macOS Monterey 12.5.1):

$ RUST_BACKTRACE=1 fj-app -m .
thread 'main' panicked at 'Error in Surface::configure: requested present mode Mailbox is not in the list of supported present modes: [Fifo, Immediate]', /Users/ykoma/.cargo/registry/src/github.com-1ecc6299db9ec823/wgpu-0.13.1/src/backend/direct.rs:281:9

@ykomatsu I've addressed this in #1035. Please let me know, if it works for you now!
