Note: Doc team updates the current version of the documentation and the
two previous versions (n-2), but we address *only high-priority, or
customer-reported issues* for -2 releases in support.
Describe the changes in the doc and link to your dev story:

1. - [ ] Mandatory: Add the required version to the Fix version/s field.

2. - [ ] Mandatory: Choose the type of documentation change or review.

• [ ] We need to update to an existing topic

• [x] We need to add a new document to an existing section

• [ ] We need a whole new section; this is a function not
  documented before and doesn't belong in any current section

• [ ] We need an Operator Advisory review and approval

• [ ] We need a z-Stream (Errata) Advisory and Release note
  for MCE and/or ACM

3. - [ ] *Mandatory: *Use the following link to open the doc and find where the
documentation update should go. Note: As the feature and doc is
understood and developed, this placement decision may change:

• Published doc: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.10
• Source: https://github.com/stolostron/rhacm-docs

4. - [ ] Mandatory for GA content:

• [x] Add steps, the diff, known issue, and/or other important
  conceptual information in the following space:
  Until now, in assisted-service, users could not select which ISO type to use; the ISO type was selected automatically, with the default being minimal-iso. This new feature allows users to select the ISO type directly in the InfraEnv Custom Resource (CR). Update documentation to include:
  • Steps to configure ISO type in the InfraEnv CR.
  • Supported ISO types and their usage.

• [ ] *Add Required access level *(example, *Cluster
  Administrator*) for the user to complete the task:

• [x] Add verification at the end of the task, how does the user
  verify success (a command to run or a result to see?)

Verification:

• • The user can verify the selected ISO type is applied by inspecting the InfraEnv CR and ensuring the isoType field reflects their selection.
  • The ISO type selection will be reflected in the InfraEnv CR status under the ISODownloadURL field, which will provide the URL for the ISO of the selected type.

• [x] Add link to dev story here: PR #6998

5. - [ ] Mandatory for bugs: What is the diff? Clearly define what the
problem is, what the change is, and link to the current documentation. Only
use this for a documentation bug.
