update swagger-ui version

[dhmlau]

Description

When running npm i in this module, I got the following warning:

npm WARN deprecated swagger-ui@2.2.10: No longer maintained, please upgrade to swagger-ui@3.

This PR will update swagger-ui version in package.json.

Guessing 3.x has breaking changes?

Upgrading to swagger-ui@3 is a lot of effort. See #209 for the previous attempt made by @STRML .

The following issue is the biggest blocker:

loopback-swagger need to produce auth metadata - see strongloop/loopback-swagger#65

The pull request also says:

The npm package no longer exports a bundle. I'm not sure if this is intentional. For this reason, I've added a dev-only script to copy from github releases.

I think this is no longer relevant, we are successfully using https://www.npmjs.com/package/swagger-ui-dist in LB4.

The pull request mentions upgrade to swagger-ui@3, but this change is upgrading only to 2.2.10. Since we are already using ^ version specifier, such change is not necessary at all - npm is going to install 2.2.10 anyway.

The reason I submit this PR is to get rid of the vulnerabilities. I thought the warnings go away when I change the version number. Let me try that again. thanks!

Based on @bajtos' above comment and #254 is opened to investigate the work involved in upgrading swagger-ui version, I'm closing this PR.
