Running "leetcode edit" with a specified language resets config options#187

## issue example I had the following code configuration options in my config file. ```toml [code] editor = "cat" lang = "java" comment_problem_desc = true comment_leading = "//" test = true ``` This was working great but when I decided I wanted to specify another language I ran the following command: ```sh $ leetcode edit 1 -l javascript ``` Which would result in the following config: ```toml [code] editor = "cat" lang = "javascript" ``` after running the command the tool successfully creates a new leetcode question to edit with the specified config options but on the next run this is not the case. When the lang option is updated it seems to be overwriting the rest of the code options. I wish I could be of more use but I currently can't read rust code. However this file might be related to the issue: [`edit.rs`](https://github.com/clearloop/leetcode-cli/blob/master/src/cmds/edit.rs). ## platform - OS: macOS Sequoia 15.4.1 - Shell: zsh
