重构：使用 GraphQL 获取 Github APIs

原因：

官方文档建议：要创建集成、检索数据和自动化工作流程，请使用 GitHub GraphQL API。 GitHub GraphQL API 提供比 GitHub REST API 更精确、更灵活的查询。
示例 0：REST API 一次只能查询一个仓库的一个维度的数据，而 GraghQL 一次查询多个仓库的多个维度的数据。
示例 1：当前 REST API 查询一个仓库的某分支的总提交数，需要某些技巧 https://stackoverflow.com/questions/27931139/how-to-use-github-v3-api-to-get-commit-count-for-a-repo ，而 GraphQL 可以直接查询这个数量。
示例 2：REST API 可以被认为是固定死的结构化的查询结果，如果抽取自己的部分字段，则需要定义与原结构类似的结构，这可能导致不必要的嵌套结构 —— 而 GraphQL 让使用者直接定义所需的数据结构。

// REST API
struct Info {
    owner: Owner,
    license: Option<License>,
}
struct Owner {
    /// user name
    login: String,
    /// Organization, User, Bot or something
    r#type: String,
}
struct License {
    spdx_id: String,
}

// GraphQL: 只需要定义 scheme 来描述如何查询
struct Info {
    owner: String,
    owner_type: String,
    license: Option<String>,
}

查看 os-checker 组织的仓库和是否产生自 fork 的情况

```graphql { organization(login: "os-checker") { repositories(last: 10) { nodes { name isFork parent { owner { login } name } } } } } ``` ```json { "data": { "organization": { "repositories": { "nodes": [ { "name": "plugin-cargo", "isFork": false, "parent": null }, { "name": "charon", "isFork": true, "parent": { "owner": { "login": "AeneasVerif" }, "name": "charon" } }, { "name": "Rudra", "isFork": true, "parent": { "owner": { "login": "sslab-gatech" }, "name": "Rudra" } }, { "name": "Starry", "isFork": true, "parent": { "owner": { "login": "Starry-OS" }, "name": "Starry" } }, { "name": "docs", "isFork": false, "parent": null }, { "name": "lkmodel", "isFork": true, "parent": { "owner": { "login": "shilei-massclouds" }, "name": "lkmodel" } }, { "name": "MWE-feature-selection-in-workspace", "isFork": false, "parent": null }, { "name": "plugin", "isFork": false, "parent": null }, { "name": "test-database", "isFork": false, "parent": null }, { "name": "os-checker-action", "isFork": false, "parent": null } ] } } } } ```

筛选 os-checker 组织中被 fork 仓库的父仓库

```graphql { organization(login: "os-checker") { repositories(last: 10, isFork: true) { nodes { name parent { owner { login } name } } } } } ``` ```json { "data": { "organization": { "repositories": { "nodes": [ { "name": "MIRAI", "parent": { "owner": { "login": "endorlabs" }, "name": "MIRAI" } }, { "name": "kern-crates.github", "parent": { "owner": { "login": "kern-crates" }, "name": ".github" } }, { "name": "cargo_metadata", "parent": { "owner": { "login": "oli-obk" }, "name": "cargo_metadata" } }, { "name": "jsonxf", "parent": { "owner": { "login": "gamache" }, "name": "jsonxf" } }, { "name": "RAP", "parent": { "owner": { "login": "Artisan-Lab" }, "name": "RAP" } }, { "name": "fork-cargo-geiger", "parent": { "owner": { "login": "mleonhard" }, "name": "fork-cargo-geiger" } }, { "name": "charon", "parent": { "owner": { "login": "AeneasVerif" }, "name": "charon" } }, { "name": "Rudra", "parent": { "owner": { "login": "sslab-gatech" }, "name": "Rudra" } }, { "name": "Starry", "parent": { "owner": { "login": "Starry-OS" }, "name": "Starry" } }, { "name": "lkmodel", "parent": { "owner": { "login": "shilei-massclouds" }, "name": "lkmodel" } } ] } } } } ```
