     * The {@link PathAdapter} allows you to customize the resolution of paths
     * in the compiled Vendure source code which is used as part of the
     * introspection step of building the dashboard.
     *
     * It enables support for more complex repository structures, such as
     * monorepos, where the Vendure server configuration file may not
     * be located in the root directory of the project.
     *
     * If you get compilation errors like "Error loading Vendure config: Cannot find module",
     * you probably need to provide a custom `pathAdapter` to resolve the paths correctly.
     *
     * @example
     * ```ts
     * vendureDashboardPlugin({
     *     tempCompilationDir: join(__dirname, './__vendure-dashboard-temp'),
     *     pathAdapter: {
     *         getCompiledConfigPath: ({ inputRootDir, outputPath, configFileName }) => {
     *             const projectName = inputRootDir.split('/libs/')[1].split('/')[0];
     *             const pathAfterProject = inputRootDir.split(`/libs/${projectName}`)[1];
     *             const compiledConfigFilePath = `${outputPath}/${projectName}${pathAfterProject}`;
     *             return path.join(compiledConfigFilePath, configFileName);
     *         },
     *         transformTsConfigPathMappings: ({ phase, patterns }) => {
     *             // "loading" phase is when the compiled Vendure code is being loaded by
     *             // the plugin, in order to introspect the configuration of your app.
     *             if (phase === 'loading') {
     *                 return patterns.map((p) =>
     *                     p.replace('libs/', '').replace(/.ts$/, '.js'),
