feat(functions-tools): convert the identifier to snake case

[peterpeterparker]

Motivation

For some reason never used a camel case before so for simplicity - instead of updating tooling and macros - let's just stick to camel case. Discovered while testing: junobuild/juno#2634

   Compiling sputnik v0.3.1 (/Users/daviddalbusco/projects/juno/juno/src/sputnik)
warning: structure field `maxResponseBytes` should have a snake case name
   --> src/sputnik/src/generated.rs:401:9
    |
401 |     pub maxResponseBytes: Option<u64>,
    |         ^^^^^^^^^^^^^^^^ help: convert the identifier to snake case: `max_response_bytes`
    |
    = note: `#[warn(non_snake_case)]` (part of `#[warn(nonstandard_style)]`) on by default

warning: structure field `isReplicated` should have a snake case name
   --> src/sputnik/src/generated.rs:403:9
    |
403 |     pub isReplicated: Option<bool>,
    |         ^^^^^^^^^^^^ help: convert the identifier to snake case: `is_replicated`

Coming from generated code

#[derive(CandidType, Serialize, Deserialize, Clone, JsonData)]
pub struct AppHttpRequestArgs {
    pub url: String,
    pub method: AppHttpRequestArgsMethod,
    pub headers: Vec<AppHttpRequestArgsHeaders>,
    pub body: Option<Vec<u8>>,
    pub maxResponseBytes: Option<u64>,
    pub transform: Option<String>,
    pub isReplicated: Option<bool>,
}
