Add suspicious_open_options lint. changelog: [`suspicious_open_options`]: Checks for the suspicious use of std::fs::OpenOptions::create() without an explicit OpenOptions::truncate(). create() alone will either create a new file or open an existing file. If the file already exists, it will be overwritten when written to, but the file will not be truncated by default. If less data is written to the file than it already contains, the remainder of the file will remain unchanged, and the end of the file will contain old data. In most cases, one should either use `create_new` to ensure the file is created from scratch, or ensure `truncate` is called so that the truncation behaviour is explicit. `truncate(true)` will ensure the file is entirely overwritten with new data, whereas `truncate(false)` will explicitely keep the default behavior. ```rust use std::fs::OpenOptions; OpenOptions::new().create(true).truncate(true); ``` - [x] Followed [lint naming conventions][lint_naming] - [x] Added passing UI tests (including committed `.stderr` file) - [x] `cargo test` passes locally - [x] Executed `cargo dev update_lints` - [x] Added lint documentation - [x] Run `cargo dev fmt`
