Loosen restriction on packaging version for package compatibility

[bolasim]

Getting package resolution errors of this nature when trying to install truss.

➜ poetry add truss==0.4.10rc9
Updating dependencies
Resolving dependencies... (0.5s)

Because truss (0.4.10rc9) depends on packaging (>=20.9,<21.0)
 and copier (8.1.0) depends on packaging (>=23.0), truss (0.4.10rc9) is incompatible with copier (8.1.0).
And because no versions of copier match >8.1.0,<9.0.0, truss (0.4.10rc9) is incompatible with copier (>=8.1.0,<9.0.0).
So, because truss-smoke-tester depends on both copier (^8.1.0) and truss (0.4.10rc9), version solving failed.

There are a lot of python packaging and versioning philosophies out there, but one of them is that it's best practice to not put an upper bound unless there is a good reason for it for package incompatibility. Let's stick with that since our package manager poetry is pretty bad at resolving these constraints .
