Upgrade to use analyzer ^5.0.0

[RoarGronmo]

Trying to upgrade dependencies and find that resolving is lacking behind due to chopper using not latest dependency of analyzer. Chopper libraries seems to use analyzer 4.4.0. Other dependecies are using analyzer ^5.0.0.

Because no versions of drift_dev match >=2.2.0 <2.2.0+1 and drift_dev >=2.2.0+1 depends on analyzer ^5.0.0, drift_dev >=2.2.0 requires analyzer ^5.0.0.
And because chopper_generator >=5.0.1 depends on analyzer ^4.4.0, drift_dev >=2.2.0 is incompatible with chopper_generator >=5.0.1.
So, because mwork depends on both chopper_generator ^5.1.0 and drift_dev ^2.2.0, version solving failed.
pub finished with exit code 1

Please upgrade chopper libraries to use analyzer ^5.0.0

I think that bumping it up to ^5.0.0 is a bit harsh because that version removed quite a few deprecated APIs. It would probably also warrant a minor version release rather than just a patch release, so I went with analyzer: '>=4.4.0 <6.0.0' which should give users a gentler transition.
