feat!: improve forge configuration DX

[MarshallOfSound]

Couple of breaking changes to improve DX

• Plugins now follow the same syntax as makers/publishers
• Better type safety of the core make/publish APIs
• Renamed electronRebuildConfig to rebuildConfig
• Fixed types for packagerConfig and rebuildConfig to appropriately Omit certain forge provided keys

With better types we can do some work to allow forge.config.ts and a completely type-safe config 🪄
