chore: tell knip @electron/get is dynamically required

The health-check job flagged @electron/get as an unused devDependency in
packages/electron. It is used, but through `require(`@${e}/get`)` — the
same computed-string form already used for @electron/packager, which keeps
the module undiscoverable by mksnapshot since it is build-only. knip cannot
resolve that statically.

Add it alongside the existing @electron/packager entry in the package's
ignoreDependencies rather than making the require a plain literal, which
would expose a build dependency to the v8 snapshot.
