[BUG] Spring generator uses old Swagger dependency

[dkirrane]

Description

I'm using openapi-generator-maven-plugin 4.1.3 and the spring generator uses an old swagger dependency.

expected:

		<dependency>
			<groupId>io.swagger.core.v3</groupId>
			<artifactId>swagger-annotations</artifactId>
			<version>2.0.10</version>
		</dependency>

actual:

		<dependency>
			<groupId>io.swagger</groupId>
			<artifactId>swagger-annotations</artifactId>
			<version>1.5.23</version>
		</dependency>

And the generated code uses import io.swagger.annotations.*
instead of import io.swagger.v3.oas.annotations.*

@dkirrane yes, we've not yet updated the annotation with io.swagger.v3.oas.annotations

Is that something you can help us with a PR?

Would you want to still have the possibility to generate 'old' code, or do you want to replace it with the newer version?
Additionally, springfox isn't really maintained anymore, so a transistion to e. g. springdoc would make sense.

My take is to replace it with the newer version. If users want the older version, they can use an old version of OpenAPI Generator for that.
