Open HRMP cross-chain communication channel between Picasso and Bifrost (attempt 2)

Same as previous attempt, but fixed transaction to send request to open channel from 2001(self - wrong) to 2087(Picasso - right)

Picasso aims to become the DeFi hub of Kusama, connecting parachains with the broader Cosmos ecosystem. Through opening this XCM channel, Bifrost assets will have access to Picasso dapps, thereby increasing the utility and TVL of vKSM and other Bifrost tokens.

For example, we will setup pools for vKSM and BNC on Pablo, as well as integrating them within our later released pallets such as CosmWasm. This opens up the possibility to also support these tokens within our IBC bridge that will launch in the future too.
