Swagger UI with provided spec broken in 1.7.0

[tobi-laa]

Describe the bug

Using Springdoc + Swagger UI with a provided spec as described here seems to be broken in version 1.7.0. Attempting to navigate to swagger-ui.html yields 404 Not Found.

To Reproduce
Steps to reproduce the behavior:

• What version of spring-boot you are using?
  2.7.10
• What modules and versions of springdoc-openapi are you using?
  • springdoc-openapi-ui
  • springdoc-openapi-security

Expected behavior

The description found here should either be updated to reflect additional steps or should work again.

Additional context

The problem appears to be the newly added org.springdoc.core.SpringDocUIConfiguration, which is only loaded when property springdoc.api-docs.enabled is set to true. With the aforementioned description to use a provided spec, said property needs to be set to false.

Maybe it is possible to simply remove @ConditionalOnExpression("${springdoc.api-docs.enabled:true}") from SpringDocUIConfiguration? As an alternative, the minimal Beans configuration might be expanded to include the contents of SpringDocUIConfiguration.

@tobi-laa you are right, it's also broken for latest version of spring boot with version 2.1.0

+1 for 2.1.0 getting NS_CORRUPTED_ERROR in Firefox network inspector and Swagger not rendering - 2.0.4 works perfectly. Webjar URLS give 404, and I see a commit has been made that removes a webjar locator

Hi! Do you plan to release updated SpringDoc 1.7.x with this fix? Or we should revert to the earlier 1.6.x versions for Spring Boot 2.7.x ? Thanks!
