Temporarily disable XBTS deposit/withdrawal and send users to xbts.io

[abitmore]

Is your feature request related to a problem? Please describe.

The deposit and withdrawal function of XBTSX assets in bitshares-ui is far behind the same function in the main XBTS website https://xbts.io, and is somewhat incompatible or misleading.

Describe the solution you'd like

Temporarily

1. disable the deposit and withdrawal function of XBTSX assets in bitshares-ui, and
2. send users who want to deposit and withdraw to the main XBTS site https://xbts.io ,

until #3400 or an alternative is implemented.

Describe alternatives you've considered

Ask XBTS to update related code in bitshares-ui.

Additional context

• Improve deposit page for coins or tokens on multiple blockchains #3400
• New standardized accounts for withdrawals are available here https://xbts.io/article/1
