Remove git dependency on egui-miniquad

[Mahad Kalam]

egui-macroquad/Cargo.toml

Lines 22 to 23 in dfbdb96

 # use a fork of egui-miniquad that's been updated to support egui 0.25.0 until https://github.com/not-fl3/egui-miniquad/pull/65 is merged 
 egui-miniquad = { git = 'https://github.com/caspark/egui-miniquad.git', rev="4fb6d4c4f3c1ed2114c5cf80f8ce967f5301e318" } 

However, not-fl3/egui-miniquad#65 has been merged, so we can use the crates.io version now.
