default `userHome=/home/git` does not work when SSH or basic auth provided

[hudac]

Issue

The default task definition task/git-clone/git-clone.yaml sets userHome=/home/git as default value.

When SSH or basic auth is provided, then the task fails during copy of required folders, i.e. here:

'/home/git/.git-credentials': No such file or directory

Workaround

• either mkdir "${PARAM_USER_HOME}" within task's script, works as root only
• or mount an emptyDir volume under /home/git (works also as non-root)
• or use the already existing /tekton/home (works also as non-root)

Additional Info

The documentation mentions /tekton/home as default.
