Describe the Change

This PR addresses the ability to add non-FIPS infrastructure packs. Previously, tenant users could only add non-FIPS add-on packs. This PR also addresses the changed toggle name in Tenant Settings from Allow non-FIPS add-on packs to Allow non-FIPS packs, replaces a screenshot, and identifies the registry needed for non-FIPS infrastructure packs.

This PR also adds how-tos to add a registry at the system and tenent levels.

The changes are great but we do need to add the documents for how to add a registry. Rita, I'm gonna share a recording with you that shows you how to do this.

[karl-cardenas-coding]

There are a few things we need to tidy up.

[karl-cardenas-coding]

This information don't belong here. This needs to be generic. This guidance should go before the table with the non fips registries in the use non-FIPS packs page.
