This rule belongs to the
openapi-v3-syntax-linting ruleset and states that:
The response content key can be a specific media type (e.g. application/json) or a wildcard media type range (e.g. image/*). Media type definitions must be in compliance with RFC6838.
|Message||The key of the response body content definition is invalid.|

- A media type consists of a top-level type and a subtype, which is further structured into a tree. A media type can optionally define a suffix and parameters as well.
- A media type follows a pattern like the following where segments between  are optional segments: <type>/[<tree>.]<subtype>[+<suffix>]*[;<parameter>]
- Some examples of valid media types are: application/json, application/vnd.api+json, text/plain.
- Media type ranges use the asterisk '' character to group media types into ranges, with '/' indicating all media types and 'type/' indicating all subtypes of that type. The media-range can include media type parameters that are applicable to that range. Each media-range might be followed by zero or more applicable media type parameters (e.g., charset).
- Some examples of media type ranges include /, text/. Here text/ media type range is more specific than / and has more precedence.
