[BUG] Typescript bindings generation order is random

[rsodre]

Describe the bug

Every time we generate typescript bindings, the order of models in models.gen.ts is changed.
It makes it impossible to review the generated models.
And is terrible to track changes and update the client after contract changes.

To Reproduce

Build dojo-starter multiple times and compare the bindings.
If there was no change in the models, they should not be updated.

# clone dojo-starter
$ git clone https://github.com/dojoengine/dojo-starter
Cloning into 'dojo-starter'...
$ cd dojo-starter 

# build once and backup the bindings
$ sozo build --typescript
   Compiling dojo_starter v1.0.2 (/Users/roger/Dev/Realms/dojo-starter/Scarb.toml)
    Finished `dev` profile target(s) in 4 seconds
$ cp bindings/typescript/models.gen.ts bindings/typescript/models.gen-0.ts

# build again multiple times and compare...
$ sozo build --typescript
   Compiling dojo_starter v1.0.2 (/Users/roger/Dev/Realms/dojo-starter/Scarb.toml)
    Finished `dev` profile target(s) in 4 seconds
$ diff bindings/typescript/models.gen.ts bindings/typescript/models.gen-0.ts

> 			x: 0,
> 			y: 0,
> 		},
110,114d114
< 		Vec2: {
< 			fieldOrder: ['x', 'y'],
< 			x: 0,
< 			y: 0,
< 		},

Expected behavior

The generated sources should be deterministic and historically accurate.

I see #2816 is ordering the models
but contracts.gen is still completely random
