First pass.

[rscampos]

First pass

Need to update the result of make help

tracee/docs/contributing/building/building.md

Line 42 in 540c8ce

make help

The difference:

• need to add: make tracee-operator and make clean-tracee-operator
• need to remove: make test-signatures

[geyslan]

Put some thoughts.

LGTM when consider my last suggestions.

@yanivagman @rscampos it would be nice to have other passes from you, as it concerns different areas.
