Git complains about user's identity in task run

[mykmelez]

In this task run, Git complained about the user's identity:

[taskcluster-vcs] 0 run start : (cwd: /repo) git merge origin/master

*** Please tell me who you are.

Run

git config --global user.email "[email protected]"
git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'root@9defe6dad430.(none)')

We should be able to fix this with commands like this in the task configuration:

  git config --global user.email "[email protected]"
  git config --global user.name "Positron Mozilla"
