Missing ipv6_disabled field in the CRD

[git-hyagi]

Describe the bug
In PR #1353 we added the ipv6_disabled field, but forgot to push the CRD manifest changes (there is only the update in the CSV), which will not allow users to define the field in the running Pulp CR.

To Reproduce
Steps to reproduce the behavior:
Install the operator and create a CR with the following:

spec:
   ipv6_disabled: true

Verify that the ipv6_disabled field will not be present in the “running” CR, so the pods will still keep crashing in case the nodes does not support ipv6.

Additional context
For installations of the operator from source, the following should fix this issue:

cd <pulp-operator directory>
make generate manifests install
