Fix start:dev script (#10399)

The `start:dev` script relies upon `electron` and `sqlite`, both of
which had their install scripts disabled by `allow-scripts`. Without
those two packages, `start:dev` crashes immediately.

The manifest has been updated to ensure install scripts run for both
packages. `start:dev` now works.
