[Bug]: azldev does not function in ADO pipelines natively due to git mis-configuration

[dmcilvaney]

Bug Description
ADO pipelines mis-configure the cloned git repo (set worktreeconfig with core.repositoryformatversion=0)

Reproduction Steps
Steps to reproduce the behavior:

Run azldev comp build in an ADO pipeline against the 4.0 distro branch.

Expected behavior
Should run build successfully.

Actual behavior
00:02:04 ERR Error: opening project repository:
core.repositoryformatversion does not support extension: worktreeconfig

Additional context
Technically this could be considered a mis-configuration in the cloned repo, but CLI git accepts it. There is a bug in go-git v5 which means it does not accept the same config. v6 fixes it, but is still in beta.

We should upgrade once its stable.
