fix(wasm-solana): return token program for CreateATA programId

Fix the parser to return the token program (from account index 5)
instead of the ATA program for CreateAssociatedTokenAccount instructions.

BitGoJS uses programId to indicate which token program owns the ATA
(Token Program or Token-2022), not the program executing the instruction.
