upgrade swagger-core from 2.2.53 to 2.2.54

[Mattias-Sehlstedt]

Swagger-core has implemented better handling for dates in swagger-api/swagger-core#5184. This means that some parts of ExtraSchemas from ec43ffb can be removed, since they are now handled upstream.

Merged, thanks @Mattias-Sehlstedt. Full suite is green on both lines.

Backported to spring-boot-3 as well (2e7d271), so 2.9.1 ships swagger-core 2.2.54 too — the initExtraSchemas entries and the app115 / app243 fixtures were identical on that line, so the cherry-pick applied cleanly.

Recorded in the changelog under Changed, flagging the visible consequence for users: Duration and LocalTime now carry format: duration / format: partial-time instead of a bare string.

Hi,
I think this feature is creating a small regression when you are using SpringDoc 3.1.0 to generate OAS in version 3.0 instead of 3.1 (i.e. by setting the application property springdoc.api-docs.version=openapi_3_0):

With SpringDoc 3.1.0 generating OAS in version 3.0, it gives this OAS:

"localTime": {
    "type": "string"
},

With SpringDoc 3.1.1 generating OAS in version 3.0, it gives this OAS:

"localTime": {
    "properties": {
        "hour": {
            "format": "int32",
            "type": "integer"
        },
        "minute": {
            "format": "int32",
            "type": "integer"
        },
        "nano": {
            "format": "int32",
            "type": "integer"
        },
        "second": {
            "format": "int32",
            "type": "integer"
        }
    },
    "type": "object"
}

I think we should keep the extra schemas when springDocConfigProperties.getSpecVersion() == SpecVersion.V30or something like that.

Best regards,
Alexandre
