Hello,
when I try to import the gorillamux based router via

import (
    "github.com/getkin/kin-openapi/openapi3"
    "github.com/getkin/kin-openapi/routers/gorillamux"
)

my IDE (Goland 2020.3) claims that it cannot resolve the gorillamux file (Error: Cannot resolve file 'gorillamux').

However if I import the legacyrouter via

import (
    "github.com/getkin/kin-openapi/openapi3"
    "github.com/getkin/kin-openapi/routers/legacy"
)

it works just fine, and resolves submodules as well.

Does anyone have an idea why this might be?
