Fix dev build

The problem is that we restrict TaylorIntegration to v0.6

Reachability.jl/Project.toml

Line 41 in cc1772d

TaylorIntegration = "^ 0.6.0"

but in the master version of TaylorModels they require at least v0.7.

However, we cannot just update TaylorIntegration because that triggers:

Reachability.solve_continuous: Error During Test at Reachability.jl/test/Reachability/alltests.jl:2

Furthermore, the dev build still crashes when resolving package versions:

Apparently one of the packages restricts StaticArrays to v0.12.1, but IntervalRootFinding restricts to v0.11.0. Manually restricting the version of StaticArrays fixes that. And here I thought that Julia would do that for you automatically 🙀

In the dev build we then get this error in the tests:
