Bug: with option -c config file ends with .cjs is still treated as JSON

[nyngwang]

As title.

So I have a project with "type": "module'' set. Now JSDoc is complaining that:

> babel jsdoc.js --config-file ./babel2.config.js -o temp.cjs &&
 jsdoc -c temp.cjs

Cannot parse the config file temp.cjs: SyntaxError: Unexpected n
on-whitespace character after JSON at position 12
Exiting JSDoc because an error occurred. See the previous log me
ssages for details.
There are no input files to process.

if I insist on using .js I got another error:

Cannot parse the config file temp.js: Error [ERR_REQUIRE_ESM]: r
equire() of ES Module /path/to/temp.js fr
om /path/to/node_modules/jsdoc/cli.js not
 supported.
temp.js is treated as an ES module file as it is a .js file whos
e nearest parent package.json contains "type": "module" which de
clares all .js files in that package scope as ES modules.
Instead either rename temp.js to end in .cjs, change the requiri
ng code to use dynamic import() which is available in all Common
JS modules, or change "type": "module" to "type": "commonjs" in 
/path/to/package.json to treat all .js fi
les as CommonJS (using .mjs for all ES modules instead).

Exiting JSDoc because an error occurred. See the previous log me
ssages for details.
