/**
 * Retrieves a TypeScript configuration file (`tsconfig.json`) from a given tree structure.
 * The function can fetch a specific `tsconfig` file by using an optional infix to target variant configurations.
 *
 * @param tree - The tree-like structure containing the file(s).
 * @param infix - Optional. A string used to specify a variant of the tsconfig file (e.g., 'prod' for 'tsconfig.prod.json').
 * @returns The TypeScript configuration object (`TsConfigJson`) from the specified file.
 *
 * @template Tree - A generic type that must conform to a tree-like interface, allowing file retrieval.

/**
 * Updates the `paths` property in the TypeScript configuration file (`tsconfig.json`) of a given project tree.
 *
 * This function allows for custom modifications to the `paths` property, which is used for module resolution aliases in TypeScript.
 * The modifications are made by passing an updater function that directly mutates the `paths` object.
 *
 * @param tree - The project tree structure which contains the `tsconfig.json` file.
 * @param updater - A function that receives the current `paths` object (from `tsconfig.json`) and mutates it to apply desired changes.
 * @param options - Optional configuration options for updating the `tsconfig.json` file. Defaults to an empty object if not provided.
 * If `options.basePath` is not set, it defaults to using an infix of 'base'.
 *
 * @typeParam Tree - A generic type that extends `TreeLike`, representing the structure of the project tree.
 *
 * @remarks
 * This function internally calls `UpdateTsConfigJson` to handle the reading and writing of the `tsconfig.json` file.
 * It ensures that the `compilerOptions` and `paths` properties exist before calling the updater function.
