Update "About" link on https://github.com/CrowdStrike/falcon-operator

[johnosn]

The link in the "About" section of CrowdStrike/falcon-operator goes to https://artifacthub.io/packages/olm/falcon-operator/falcon-operator.

https://artifacthub.io/packages/olm/falcon-operator/falcon-operator shows falcon-operator 1.5.0.

Please adjust the link to something that would be current.
