Add support for querystring parameter location

[baywet]

The parameter location enum should be updated to add a new querystring value.

https://spec.openapis.org/oas/latest#common-fixed-fields

Serialization and deserialization should already be implemented for us.

Trying to serialize this value for version< 3.2.0 should result in an exception since there's no way to represent this and get a valid description.

Additionally, when serializing this property, if the properties style, header, explode, allowReserved or schema are used, and exception should be thrown since the specification explicitly prevents those cases.
