swagger-ui-react option to enable pkce

[kriechi1992]

Context

We are using backstage.io as a dev portal - which is using SwaggerUI React to render OpenAPI specs.
Everything is working fine - except the authorization part: Our SSO uses Authorization Code Grant with PKCE.

With my standalone setup and the usePkceWithAuthorizationCodeGrant flag everything works as expected. But I could not manage to enable it in the swagger-ui-react component.

What I tried

If I run a standalone SwaggerUI instance with OAUTH_USE_PKCE=true (which is the equivalent to usePkceWithAuthorizationCodeGrant in the initOAuth method) everything works fine.

What I'd wish for

Add a prop to the list that maps to the usePkceWithAuthorizationCodeGrant flag in the initOAuth method
