"Caller is not the contract's current owner"

[taitruong]

cw-ownable is used in cw-nfts, like for TransferNFT, so the message is a bit misleading.

"Caller is not the current owner" would be better

cw-plus-plus/packages/ownable/src/lib.rs

Lines 68 to 71 in eed2b87

	#[error("Caller is not the contract's current owner")]
	NotOwner,
	#[error("Caller is not the contract's pending owner")]
