fix: set gateway address to a placeholder

[fadeev]

With this placeholder, when I import the Gateway from an example project, it seems to compile fine:

[dependencies]
Sui = { git = "https://github.com/MystenLabs/sui.git", subdir = "crates/sui-framework/packages/sui-framework", rev = "framework/testnet" }
gateway = { git = "https://github.com/zeta-chain/protocol-contracts-sui.git", rev = "gateway-address" }

[addresses]
call = "0x0"
gateway = "0x2c8aa332520a3c3984c84c9acedeaee5421a327e031692530724b4f280516c8f"

module call::hello_world {
    use gateway::gateway::deposit;
    ///...
}

If I switch back to the main branch:

[dependencies]
Sui = { git = "https://github.com/MystenLabs/sui.git", subdir = "crates/sui-framework/packages/sui-framework", rev = "framework/testnet" }
gateway = { git = "https://github.com/zeta-chain/protocol-contracts-sui.git", rev = "main" }

[addresses]
call = "0x0"
gateway = "0x2c8aa332520a3c3984c84c9acedeaee5421a327e031692530724b4f280516c8f"

The build fails:

Failed to build Move modules: Processing dependency 'gateway' of 'call'

Caused by:
    Conflicting assignments for address 'gateway': '0x2c8aa332520a3c3984c84c9acedeaee5421a327e031692530724b4f280516c8f' and '0x0'..

Running sui move test works
But running sui move build fails with

sui move build
UPDATING GIT DEPENDENCY https://github.com/MystenLabs/sui.git
Failed to build Move modules: Unresolved addresses found. To fix this, add an entry for each unresolved address to the [addresses] section of ./Move.toml: e.g.,

[addresses]
std = "0x1"

Alternatively, you can also define [dev-addresses] and call with the -d flag

Caused by:
    Unresolved addresses: [
      Named address 'gateway' in package 'gateway'
    ].

@lumtis can we use sui move build -d?

@lumtis can we use sui move build -d?

For the time being it might be fine

Compile in 'dev' mode. The 'dev-addresses' and 'dev-dependencies' fields will be used if this flag is set. This flag is useful for development of packages that expose named addresses that are not set to a specific value

But I'm not sure this will allow use to deploy the package in prod with this option.
Although when deploying in prod we can still change the move.toml

Approving now in case this unblock the localnet
