Consistent Makefile between Medik8s Operators - Bundle Creation Addition

[razo7]

For better collaboration I am aligning our Makefiles, and this is the fourth PR.

Small changes to bundle creation (similarly to NHC and SNR PRs)

• Moving NMO icons to assets directory
• Add two new targets for updating and resting the CSV under bundle directory (containerImage, createdAt, and icon fields)
• Reset bundle's createdAt field (after updating operator-sdk to v1.26.0 it adds the createdAt field after running make bundle)

Similar problem as it was in #50 for OCP 4.13, thus it is irrelevant to the PR changes. /override ci/prow/4.13-openshift-e2e
