Prop 115: Add PLQ Metadata to Gravity Bridge

This proposal connects the PLQ token from Planq to the Gravity Bridge. If accepted, it would establish metadata for the IBC denom ibc/2782B87D755389B565D59F15E202E6E3B8B3E1408034D2FAA4E02A0CA10911B2. This metadata would then be usable to deploy an ERC20 representation on Ethereum for the PLQ token. Voters should verify that the ibc hash is on channel-102, that this channel matches the forwarding proposal submitted at the same time, and that the denom trace is for the correct token. This can be done using gravity query ibc-transfer denom-trace ibc/2782B87D755389B565D59F15E202E6E3B8B3E1408034D2FAA4E02A0CA10911B2.
