Update Arch Ethereum Web3 token description

[mericci]

Hi! I need to change the description of Arch Ethereum Web3.

I need to change this line content for this text:

The Arch Ethereum Web3 Token is comprised of governance tokens from the major decentralized protocols. Its objective is to track the returns of the Ethereum Web3 Index (a broad market index, considered a gauge for the overall web3 ecosystem). This well-diversified asset, provides market-weighted exposure to a wide selection of sectors, and its constituents represent roughly 70% of the market capitalization in the Ethereum Web3 Index.

Thank you!
