Add chaintype.ChainZircuit to chaintypes with rollup support

[ogtownsend]

Motivation

• Zircuit's chaintype was recently changed from optimismBedrock to zircuit
• This means IsRollupWithL1Support() started returning false for zircuit
• Which in turn meant no L1 oracle was created for Zircuit

Solution

• Add zircuit to supportedChainTypes
