Possible issue using 4.x git resource resource version with TFS

[topherbullock]

Some users have reported issues using the git-resource in Concourse 4.2.1 with TFS. Below is an example of the error reported:

resource script '/opt/resource/check []' failed: exit status 128

stderr:
Cloning into '/tmp/git-resource-repo-cache'...
fatal: could not read Username for '{{tfs_uri}}': No such device or address

The same resource config works with 3.13, so this seems to be an issue with the git version in the image and its compatibility with the latest TFS. Also, it seems that overriding the git resource with the latest image from DockerHub fixes the issue.

TFS version details:

Microsoft Visual Studio Team Foundation Server
Version 16.131.27701.1

A quick dig into this didn't uncover any obvious reasons why that git version would fail.
