* refactor: replace module_config_derive with serde
Changes include:
* Removing `starship_module_config_derive` and replacing it with `serde::Deserialize`
* Removing `RootModuleConfig::load_config`. While potentially useful, it was only used in tests. And it would require something like `serde::DeserializeSeed` which is not derived by serde.
* Merging `RootModuleConfig` into `ModuleConfig`
* Implementing a `ValueDeserializer` that holds a reference to a `toml::Value` in `serde_utils.rs`
* Deserialization errors (invalid type) are now logged and include the current key and the struct names
* Unknown keys are now considered an error. "Did you mean?"-messages are still possible
* fix typo
