regression: `task create` no longer returns json output

[andycmaj]

Expected behavior (0.10.3)

(note. 0.10.7 cli calling 0.10.3 api)

l0 --output json task create returns the task as json

Actual behavior (0.10.7)

the command seems to return an empty json arrray in 0.10.7

There was a breaking change when Layer0 v0.10.4 was released with regard to how tasks were handled; we moved away from using task names to using task ARNs, for more specificity and reliability. When we did so, we should have released a new minor version, not just a patch, since this was a breaking change.

As such, I'll be adding some known-issue-style documentation recommending that users treat v0.10.4+ as incompatible with v0.10.3-. Versions <= 0.10.3 may be considered intercompatible, and versions >= 0.10.4 may be considered intercompatible, but the gulf between the two versions is a pit of incompatibility.
