[email protected] currently locks [email protected] which has keytar as a required dependency.

This breaks builds on Clang systems (e.g. Macs) because keytar's node-gyp build fails due to some invalid C code.

[email protected] moves keytar to an optional dependency instead.

See NixOS/nixpkgs#449650 for more information.

Tasks:

• Bump vsce to 2.16.0 or higher.
• Release [email protected].
