String keys with 0s at the front can not be converted to numbers

[theCapypara]

serde_json version 1.0.101 broke the following:

use std::collections::HashMap;
use serde_json; // 1.0.105

fn main() {
    let data = r#"
        {
            "01234": "foo"
        }"#;

    let _: HashMap<i64, String> = serde_json::from_str(data).unwrap();
    
}

Before this release serde_json "correctly" (I guess that is up to debate) stripped the numbers in front and converted the key in this case to 1234i64. Now it just fails to parse.
