pulsar-edit/ppm#43

Description of the Change

This syncs Pulsar's ppm submodule to the latest commits from https://github.com/pulsar-edit/ppm master branch.

Particularly: This includes the updated Electron headers download URL.

Alternate Designs

None

Possible Drawbacks

None. The old endpoint (headers download bucket) was deprecated, this is the new official one. It has only stronger guarantees of reliability than the old one.

If this new URL goes down, it means the whole Electron ecosystem is just as affected as we are. If the old URL independently went down, it would mean we (Atom and all of its forks) were uniquely affected. Although that has never happened to my knowledge, with the deprecation it is quite likely to permanently go down some time in the future, which could easily happen as early as December 15th, as per the updated Sunset Announcement.

Verification Process

First, verified the fix in terms of just the ppm repo -- see testing notes over at pulsar-edit/ppm#43 (comment).

Then, tested this update in Pulsar as well, locally on Linux, with the .deb package of Pulsar from this branch, using the following command:

/opt/Pulsar/resources/app/ppm/bin/apm install language-carp --verbose
