Body-parser deprecated

[linqFR]

Console shows deprecation of body-parser:
body-parser deprecated undefined extended: provide extended option node_modules\oas3-tools\dist\middleware\express.app.config.js:22:33

Why to use both body-parser and express parsers?

oas3-tools/src/middleware/express.app.config.ts

Lines 30 to 32 in 9349490

	this.app.use(bodyParser.urlencoded());
	this.app.use(bodyParser.text());
	this.app.use(bodyParser.json());

and then again

oas3-tools/src/middleware/express.app.config.ts

Lines 35 to 36 in 9349490

	this.app.use(express.json());
	this.app.use(express.urlencoded({ extended: false }));

Express can do the job on his own:
https://expressjs.com/fr/api.html#express.urlencoded
https://expressjs.com/fr/api.html#express.json
https://expressjs.com/fr/api.html#express.text

I'm creating a POC in order to start using this module and I found this small issue as well, I'd be great to have a document in order to proceed to a leave a PR. I think this module is awesome!
