[sozo] change manifests files name for folders

[glihm]

Is your feature request related to a problem? Please describe. Currently, the manifests files were generated with fully_qualified_named.toml/json. But ideally, we want a folder to represent the path of the fully qualified name.

Describe the solution you'd like For example:

dojo_examples::actions::actions.toml

// should be
dojo_examples/actions/actions.toml

Additional context Here's where we replace the ::: https://github.com/dojoengine/dojo/blob/f0637f928470217fccd60fe15b1b9c6fefd5c984/crates/dojo-world/src/manifest/mod.rs#L99. We should create a path instead.

Also, we sorted the entries to ensure we don't have manifests diffs just based on the order: https://github.com/dojoengine/dojo/blob/f0637f928470217fccd60fe15b1b9c6fefd5c984/crates/dojo-world/src/manifest/mod.rs#L508

We should use a SortedMap to keep the manifests to ensure we always output the manifests in the same order into the deployment to avoid diffs only for orders.

@lambda-0x could you take this one? :)

This will be reworked during namespaces implementation to not be dependent on file structure for the manifests files.
