• [core] fix: export IconComponent type (previously named GenericIcon) in public API
• [icons] fix: export SVGIconContainerComponent type (previously named GenericSVGIconContainer) in public API

Before this change, users may have received a TS compilation error when trying to re-export Icon or SVGIconContainer as TS would attempt to reference a private type symbol:

error TS4023: Exported variable '[redacted]' has or is using name 'GenericIcon' from external module "/home/circleci/project/node_modules/.pnpm/@blueprintjs+core@5.1.4_ugrpyuvudjf6jbttetu7vnqf5m/node_modules/@blueprintjs/core/lib/esm/components/icon/icon" but cannot be named.
