Bump go-stellar-sdk to pick up XDR asset ordering fix (#218)

Picks up stellar/go-stellar-sdk#5974, which fixes Asset.LessThan to
compare assets by their XDR encoding (raw issuer key) instead of strkey
text, and switches the token_transfer processor to value-based asset
equality so trustline revocation burns the correct liquidity pool leg.
Also carries the required go-xdr bump to
v0.0.0-20260806060815-dc590f17552a.
