@Tag name parameter not consistently performing lookup on properties file

[ianwallen]

Describe the bug
@tag name is being parsed differently depending on the parameters supplied to the annotation.

i.e.
In the unit test App14 (https://github.com/springdoc/springdoc-openapi/tree/master/springdoc-openapi-webmvc-core/src/test/java/test/org/springdoc/api/app14)

@Tag(name = "greeting")
Produces the following in the unit test.
"tags":["Change the language","Hello! Welcome to our website!"]

But changing the @tag to include a description causes the name parameter to no longer load from properties file.
@Tag(name = "greeting", description = "greeting")
Produces
"tags":[{"name":"greeting","description":"greeting"}]

To Reproduce
Modify the following line in the unit test.

springdoc-openapi/springdoc-openapi-webmvc-core/src/test/java/test/org/springdoc/api/app14/HelloController.java

Line 31 in 6725f08

@Tag(name = "greeting")

@Tag(name = "greeting", description = "greeting")

Run the test and check the body that was returned in the error message.

Expected behavior
I would expect that both Name and Description would have converted from the properties file to product "Hello! Welcome to our website!"
I also expect that adding a new parameter should not change the results of how the name parameter is loaded from the properties file.
