feat(build): support local sdk wheel for building model image (#187)

Because

- currently, model image can only install instill-sdk from pypi service,
which makes changes must be merged into main branch

->

- with these changes, we can make dist to build local dev wheel and
instill build --sdk-wheel {path-to-wheel} to force model image to use
dev version sdk, which makes the dev process much easier

This commit

- support local sdk wheel for building model image
