It’s pretty obvious you ain’t backing up to take another shot at it.
Get out of the truck.
Drop that ramp so you can use it to stabilize everything and use it for a tail skid.
Fire up the little Track Hoe.
Swing it over the side and extend/ drop the boom down until the bucket is pushing down on the bank next to the back tire on the trailer just enough to push the trailer up a smidge using the rear bumper as a teeter totter on the edge of the pavement it’s dragging on and then pull the trailer forward a bit.
That should be enough to keep it from tipping over and get that front axle up onto the bank a bit to steady the trailer.
Reset the bucket and do it again.
Pick up the ramps.
Repeat holding the inner side up with the bucket until the rear axle has that rear wheel on the bank so the thing can’t tip over then stow the bucket.
Yer gonna drag the ass of the trailer but it will get you out of the hole and back onto the pavement at least.
