feat: world.toml config file and set namespace

[jerargus]

Closes: #WORLD-574

What is the purpose of the change

Make it possible to drive world-cli via a configuration file. world-cli checks for configuration files in the following order:

1. a flag: --config=/path/to/some/file
2. an environment variable: WORLD_CLI_CONFIG_FILE=/path/to/some/file
3. a file called "world.toml" in the current directory
4. a file called "world.toml" in the parent directory (or its parent directory, etc...)

In the current iteration of this code, key/value pairs in the toml files are interpreted as environment variables and passed directly to the docker-compose command.

This starter-game-template-pr: Argus-Labs/starter-game-template#31 includes a sample config file.

Testing and Verifying

There are unit tests to verify the loading and parsing of

i think it might be kinda nice to have toml headers for the specific resource you're configuring. something like:

[evm]
DA_AUTH_TOKEN=blah
BLAH=BLAH

[cardinal]
CARDINAL_NAMESPACE=BLAH

yeah lets do this, we might actually need this because we might have multiple different cardinal game projects in the same repo that needs different configs.

looks good. can we throw an example.toml in the root? i see its in the starter-template but would be nice to have here just for reference, and even testing
