test: bridge l2 erc20 token

[Stefan-Ethernal]

Description

Implement bridging of custom ERC20 token from L2 to L1 and vice versa.

Steps

1. Deploy mock ERC20 token on L2 network
2. Mint some supply to a sender account (e.g. 10 ETH value of mock ERC20 token)
3. Approve L2 bridge as a spender (e.g. 10 ETH value of mock ERC20 token)
4. Bridge L2 -> L1 (e.g. 1 ETH value of mock ERC20 token)
5. Claim bridge@L1
6. Wrapped token is deployed on L1
7. Approve L1 bridge as spender of the L1 wrapped token (e.g. 1 ETH value of L1 wrapped token)
8. Bridge L1 -> L2 (e.g. 1 ETH value of L1 wrapped token)
9. Claim bridge@L2
10. Bridge L2 -> L1 (e.g. 1 ETH value of mock ERC20 token)
11. Claim bridge@L1
