Add support for Sauce Connect 5

[MancLad89]

Sauce Connect 5 has been released in the SauceLabs ecosystem but this package seems to remain on 4.x.
I have already reached out to your support team who asked me to direct the request here.

FYI: Readiness check of Sauce Connect Proxy 5 does not work: #242, which should be a blocker for this

(I am using my own implementation for Node.js client for Sauce Labs after experiencing issues like #241 but now I am blocked by #242 for v5)

@waggledans any timelines when SC v5 is supported in the official saucelabs package? We have a lot of folks using it in WebdriverIO and they are getting deprecation notices as this package doesn't support v5.

@waggledans Do you have any timeline where we will get support for sc5 provided sc4 will reach its end of life on Dec 31, 2024?

@christian-bromann and @samGladson this PR is blocked on the Sauce Connect team to update their REST API with sc5 versions. I submitted a support request to them a while ago. Will check with them and update on the progress
