Update deps and tests

[rhaist]

Describe the PR
Update dependencies and adapt test

[rhaist]

So it seems like github.com/mattn/go-runewidth depends on github.com/rivo/uniseg which requires Go 1.18.
I guess you don't want to require that as a minimum version for fiber-swagger ?

Based on https://endoflife.date/go I would recommend to upgrade the supported versions to 1.18 and 1.19.

@rhaist This package returns a fiber.Handler so you can use it with your project.
Your PR simply drops support for anyone using an older version than go 1.18 which will introduce breaking changes.

For example, I use go 1.17 to build my projects for prod env.

By example we can drop version 1.15 to get in sync with swaggo/swag.
