chore(heureka):fix-make-error-mockery

[copyonwrite]

# task can be: feat, chore, refactor, or research.

Task Description

The 'make' command doesn't build heureka OOTB because 'mockery' cannot be found.

As of now, 'mockery' is installed as a side effect of 'go generate'.

The desired outcome of this task is that 'make' works OOTB and 'mockery' as well as other dependencies are installed explicitly in their own make goal.

Acceptance Criteria:

'make' runs and builds everything OOTB.

Expected Test:

Execute 'make' on a clean system.
