Wails v2 defaults to linking against webkit2gtk-4.0, but modern Linux
distributions (e.g. Fedora) only ship webkit2gtk-4.1. The webkit2_41
build tag tells Wails to link against the correct library.
Provides two targets:
- make dev: run wails dev with the correct tag
- make build: build the production binary with the correct tag
- make clean: remove build artifacts
