fix(sdk): Add collateralFiat support into Token.ts & TokenStandard.ts (#4308)

### Description
Adds CollateralFiat to token mapping which will output the correct
`standard` to the warp deploy artifact.

### Related issues
https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/4307

### Backward compatibility
Yes

### Testing
Manually tested with Beta (collateral) -> Gamma (CollateralFiat)
1. Deploy an ERC20 to represent USDC on beta
```
forge create contracts/test/ERC20Test.sol:ERC20Test \
--constructor-args "Test" "TS" 10000000000000000000000000 6 \
--rpc-url https://beta-op.rpc.caldera.xyz/http \
--private-key $HYP_KEY
```
2. Deploy a CollateralFiat on gamma
```
forge create contracts/test/ERC20Test.sol:FiatTokenTest \
--constructor-args "FiatTest" "FTS" 0 6 \
--rpc-url https://rpc-gamma-2bgo7wnh9d.t.conduit.xyz \
--private-key $HYP_KEY
```
3. warp init and deploy
4. Start up the ts relayer `hyperlane relayer --chains beta,gamma`
5. Add the deploy artifacts to UI
```
