OpenAPI: provide a way to customize the header info text

[loicmathieu]

Description

The OpenAPI header info text is auto generated by Quarkus to something like app-name version (quarkus quarkus-version).

Today, it can only be customize by providing a style.css file, but it needs to provides all the styles in it and not juste the one that need to be customize as style.css will replace the generated one. It's also a little complex to provide a CSS to manage text content.

The current text value can be an issue if OpenAPI is planed to be deployed on production as it contains technical information so it's a security vulnerability as defined in the OWASP top 10 vulnerabilities: information disclosure.

Quarkus may provide a way to easily customize this text.

Implementation ideas

Provide a way to customize the header info text via application.properties

quarkus.swagger-ui.header-info=foo bar

Another solution would be to provide an header-info-enable property and not a custimization. Both solutions are OK for me.
