Is this feature request related to a problem?

Yes

Problem Description

it is the same as in k8sgpt-ai/k8sgpt#440 which also needs to get fixed in k8sgpt-operator

Solution Description

the operator should create a deployment which emptyDir volume and this XDG_ variable set as in k8sgpt-ai/k8sgpt@44725d9

Benefits

then on openshift k8sgpt deployment will start with restricted-v2 SCC and arbitrary uid. in addition, now k8sgpt deployment can run with securityContext.readOnlyRootFilesystem, which is also a security benefit.

I would be happy to create a PR for this issue by myself. Eager to learn about operator development and local testing ;)
