GroupedApi orders by displayName instead of name

[juocal]

Describe the bug

When creating multiple GroupedOpenApi, the resulting url list via /v3/api-docs/swagger-config is not ordered corretly. It orders by the name, but not by the displayName attribute of the urls.

When using it with Swagger UI the dropdown menu is unordered, although a "groupsOrder" is configured.

To Reproduce
Create two groupedApi with names which are not in the same alphabetical order as the displayNames:

    @Bean
    public GroupedOpenApi adminApi() {
        return GroupedOpenApi.builder()
            .displayName("yyyy - Admin Api")
                .group("admin")
                .pathsToExclude("/api/v1/**", "/v1/**")
                .pathsToMatch("/api/v2/**", "/v2/**")
                .build();
    }
    
    @Bean
    public GroupedOpenApi yellowApi() {
        return GroupedOpenApi.builder()
            .displayName("aaaa - Yellow Api")
                .group("yellow")
                .pathsToExclude("/api/v1/**", "/v1/**")
                .pathsToMatch("/api/v2/**", "/v2/**")
                .build();
    }    

Now "yyyy - Admin Api" comes first in the list, and "aaaa - Yellow Api" comes second, as "admin" is alphabetically before "yellow".

• What version of spring-boot you are using?

Expected behavior

I expect to return a ordered list, ordered by the displayName instead of the name attribute.
In the above mentioned example, it should come the other way round: "aaaa - Yellow Api" first, "yyyy - Admin Api" second (given same groupsOrder and groupsOrder set to ASC.

Additional context

The relevant line is here:

springdoc-openapi/springdoc-openapi-starter-common/src/main/java/org/springdoc/core/properties/SwaggerUiConfigParameters.java

Line 307 in e14f975

swaggerUrlComparator = Comparator.comparing(SwaggerUrl::getName);

This line was probably forgotten to change, when "displayName" was introduced, additional to "name"
