Untyped serde_json::Value types used for TimeEntry.project

[schpet]

hi there! thanks for putting this up. i noticed some of the types are missing, e.g. serde_json::Value is used in a number of fields that i'd expect to have types:

harvest-rs/src/model.rs

Line 1059 in 2893890

pub project: Option<serde_json::Value>,

but given this project appears to done via code generation, i'm wondering what script updates this repo? i'm assuming it's a hand-crafted OpenAPI yaml doc that needs updating to fix this since i don't see an official one from harvest.
