OCPBUGS-43449: Remove UltraSSD_LRS from DiskStorageAccountType for OS Disks

[hypershift-jira-solve-ci]

What this PR does / why we need it:

Removes UltraSSD_LRS from the AzureDiskStorageAccountType enum validation in the NodePool API. According to Azure documentation, Ultra Disks (UltraSSD_LRS) are not supported for OS Disks — they can only be used as data disks.

Changes:

• Removed UltraSSD_LRS from the kubebuilder Enum validation on AzureDiskStorageAccountType
• Removed the DiskStorageAccountTypesUltraSSDLRS constant
• Removed the XValidation rule on AzureNodePoolOSDisk that referenced UltraSSD_LRS for conditional disk size constraints
• Reduced max SizeGiB from 65,536 to 32,767 (the higher limit was only needed for UltraSSD_LRS)
• Updated field documentation to note UltraSSD_LRS is not supported for OS disks
• Regenerated CRDs and API docs

Which issue(s) this PR fixes:

Fixes OCPBUGS-43449

Special notes for your reviewer:

Azure Ultra Disks (UltraSSD_LRS) cannot be used as OS disks per Azure's own documentation. This change removes it from the API validation to prevent users from specifying an unsupported disk type. The valid values for OS disk storage account type are now: Premium_LRS, PremiumV2_LRS, Standard_LRS, StandardSSD_LRS.

Checklist:

• Subject and description added to both, commit and PR.
• Relevant issues have been referenced.
• This change includes docs.
• This change includes unit tests.

Walkthrough

Removed UltraSSD_LRS as an allowed Azure OS disk storage account type and lowered the OS disk maximum size constraint from 65536 to 32767 GiB across the API types, generated CRD manifests, and documentation; related cross-field validations referencing UltraSSD_LRS were removed.

Changes

Cohort / File(s)	Summary
API Type Definition api/hypershift/v1beta1/azure.go	Deleted DiskStorageAccountTypesUltraSSDLRS constant; updated AzureDiskStorageAccountType enum to exclude UltraSSD_LRS; changed AzureNodePoolOSDisk.sizeGiB max from 65536 → 32767 and updated related validation comments.
Generated CRD Manifests api/hypershift/v1beta1/zz_generated.featuregated-crd-manifests/nodepools.hypershift.openshift.io/AAA_ungated.yaml, api/hypershift/v1beta1/zz_generated.featuregated-crd-manifests/nodepools.hypershift.openshift.io/OpenStack.yaml, cmd/install/assets/hypershift-operator/zz_generated.crd-manifests/nodepools-*.crd.yaml	Removed UltraSSD_LRS from osDisk.diskStorageAccountType enums; set osDisk.sizeGiB maximum to 32767; removed x-kubernetes-validations cross-field rule that enforced UltraSSD_LRS-dependent size constraints.
Documentation docs/content/reference/aggregated-docs.md, docs/content/reference/api.md	Updated descriptions to state UltraSSD_LRS is not supported for OS disks; clarified sizeGiB valid range as 16–32767 and noted default behavior (current default 30 GiB); removed references implying UltraSSD_LRS OS-disk support.

Hi @hypershift-jira-solve-ci[bot]. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@bryan-cox Done. Rebased on main and updated the GCPPlatform.yaml featuregated CRD manifest which was added after the original regeneration commit and still had stale UltraSSD_LRS references. The verify job should pass now.
