2064412 - Make the `build-components` kind clone from GitHub rather than hg.mozilla.org

Status: REOPENED

(Firefox Build System :: Task Configuration, task)

Description

[Andrew Halberstadt [:ahal]]

Currently, tasks generated by the build-components Taskcluster kind (taskcluster/kinds/build-components/*.yml) clone the tree from hg.mozilla.org as part of their checkout step.

As part of the broader effort to move off of Mercurial and onto Git/GitHub, these tasks should instead clone from GitHub when possible. If there is no Github location to clone from, then it will fallback to Hg (for now)
