Azure Repos: repository names ending with .git are stripped when generating SourceLink URLs

[Eales]

When RepositoryUrl points to an Azure Repos repository whose actual name ends with .git,
GetSourceLinkUrl strips the .git suffix from the generated SourceLink URL.

Example:

Input:
https://dev.azure.com/org/project/_git/repo.git

Actual:
https://dev.azure.com/org/project/_apis/git/repositories/repo/items?api-version=1.0&versionType=commit&version=&path=/*

Expected:
https://dev.azure.com/org/project/_apis/git/repositories/repo.git/items?api-version=1.0&versionType=commit&version=&path=/*

This causes 404 responses for repositories whose actual name includes .git.

I have a fix and regression tests prepared.
