Seems no dependency on gin-swagger (cyclic dependency ?)

[gasuketsu]

Describe the bug

It looks that current swag does not have dependency on gin-swagger though go.mod has dependency on gin-swagger@v1.2.0.
Due to this dependency, performing go mod tidy in project using echo-swagger fails with following error.

        github.com/swaggo/echo-swagger tested by
        github.com/swaggo/echo-swagger.test imports
        github.com/swaggo/gin-swagger/example/docs: module github.com/swaggo/gin-swagger@latest found (v1.2.0), but does not contain package github.com/swaggo/gin-swagger/example/docs

To Reproduce
Steps to reproduce the behavior:

1. Create a 'go moduled' project depends on github.com/labstack/echo/v4 and github.com/swaggo/echo-swagger.
2. Perform go mod tidy in the project

Expected behavior
go mod tidy completes w/o error.

@gasuketsu GO is right, there is no docs package in swaggo/gin-swagger/example for version 1.2.0 as swagg/go.mod is describing.

#800 along with swaggo/echo-swagger#33 should fix this issue

Closing: fixed.
