Fix Power changes from PR26184

[bobfuru]

Mostly, this PR fixes changes that were made in modules/installation-user-infra-machines-static-network.adoc in #26184. (See my inline comments in that merged PR for more details.)

IIUC, the changes that were made were cosmetic. In other words, they are not hiding any functionality to a certain set of users (i.e., Z-Power).

What was changed in that file minimizes the level of information that follows. The three bulleted items describe the three ways that a user can configure advanced networking: at the live installer boot prompt, by using specific core.inst boot options, or by passing arguments directly to coreos-installer. The tables that follow that intro cover these three scenarios.

It is my conclusion that the changes in this new PR should be acceptable without conditionals necessary, and that we should therefore be able to merge this PR and CP it to 4.6 with no additional tags added. But I might be missing the bigger picture.

@vikram-redhat or @codyhoag Do you see any issue with merging and CP'ing this to 4.6?

@bobfuru one question: I see the Advanced RHCOS installation reference used in the IBM Power installation docs too here. I don't know much background on the subject here, so I don't know what should and shouldn't be included 😅. Do you think the references to bare metal are out of place there? If not, I think these changes are good from my perspective.

@codyhoag I don't know too much about the IBM Power docs, either. I was aware that Advanced RHCOS installation reference is used in the link you mentioned, and it doesn't seem out of place to me. Ideally, that should have been included in the module metadata for cross-referencing but it doesn't seem that that happened.

Another question I wonder about is why Advanced RHCOS installation reference was included in only 1 of the 2 "Installing on IBM Power" assemblies ("Restricted network IBM Power installation" but not "Installing a cluster on IBM Power"). For bare metal install docs, we add it to child assemblies. Example here.

@vikram-redhat I agree with Cody, I think we are good with these changes, but I also suspect it should be added to the installing-ibm-power.adoc file, too. So I've done so.

I noticed that we updated the title of this module but it wasn't reflected in this reference.

[bobfuru]

As I noted in the comments of this PR, I think this should be added to this assembly as well.
