Fixes Azure DevOps Work Item autolinks pointing to wrong project

[sergeibbb]

Description

Fixes #4776. It's based on user's PR #4777 with a little improvements.

The difference with the original PR: it stops relying on isVsts method to form the resulting link. Instead, it transforms the repository's baseUrl properly by removing the project name from it.

Hi @eamodio and @d13.

It's an improved version of user's PR #4447.

The only difference is this commit, where I always form the URL based on the repository's baseUrl, instead of building it from primitive fields based on various patterns. By doing that I stop relying on isVsts method and stop requiring knowledge of different URL structures.

Could you please look at my commit and approve or decline this approach.

Also I've tested the result for Azure DevOps Cloud (both for visualstudio.com and dev.azure.com URLs) and for Azure DevOps Server. The steps are reflected in the "Verification steps" section of the issue.

I think this looks good.
