Printed `Instruction::EmitImm` is invalid Masm

[mooori]

Instruction::EmitImm is printed as emit.<felt> which is invalid Masm and cannot be parsed

miden-vm/crates/assembly-syntax/src/ast/instruction/print.rs

Line 338 in ca29898

Self::EmitImm(value) => inst_with_felt_imm("emit", value),

Proposed fix

Print as push.<felt> emit drop, which is equivalent and can be parsed back.
