Update README.md

Hello,

I have three suggestions to improve this text gramatically.

1. "One of primary importance is cross-chain swaps"
Correction: "One of the primary importance is cross-chain swaps"

2. "Ensure the incoming IBC packet is cryptogaphically valid"
Correction: "Ensure the incoming IBC packet is cryptographically valid"

3. "Also when a contract make IBC transfer request"
Correction: "Also, when a contract makes an IBC transfer request"

Thanks.

 The move hook is an IBC middleware which is used to allow ICS-20 token transfers to initiate contract calls.
 This allows cross-chain contract calls, that involve token movement.
 This is useful for a variety of use cases.
