Custom hooks requires undocumented filename when using firestore2json.js

Bug report

Describe the bug

Custom hooks are documented to must have the name of the collection (e.g. for a collection weapons, the hook filename is weapons.js)

Looking into firestore2json.js, the filename being looked into has a suffix of "_processDocument.js")

var processDocument;
if (fs.existsSync("./".concat(args[0], "_processDocument.js"))) {
    // read file to string
    processDocument = require("./".concat(args[0], "_processDocument.js"));
    // processDocument = fs.readFileSync(`./${args[0]}_processDocument.js`, 'utf8');
}

The Typescript counterpart does not require this suffix:

let processDocument;
if (fs.existsSync(`./${args[0]}.js`)) {
    // read file to string
    processDocument = require(`./${args[0]}.js`);
}
