The openshift source provider is missing from the list of providers mentioned in the CL migrating vms section

[sgratch]

Describe the bug

Under this doc section https://access.redhat.com/documentation/en-us/migration_toolkit_for_virtualization/2.5/html-single/installing_and_using_the_migration_toolkit_for_virtualization/index#migrating-virtual-machines-cli_mtv, in the procedure section, step no. 1.2, (Secret manifest )the following text:
Specify the type of source provider. Allowed values are ovirt, vsphere, openstack, and ova. This label is needed to verify the credentials are correct when the remote system is accessible and, for RHV, to retrieve the Manager CA certificate when a third-party certificate is specified.

Should be rephrased with the following:
Specify the type of source provider. Allowed values are ovirt, vsphere, openstack, **openshift** and ova. This label is needed to verify the credentials are correct when the remote system is accessible and, for RHV, to retrieve the Manager CA certificate when a third-party certificate is specified.

The fix includes adding openshift as a source provider.

We added supporting OpenShift as a source provider in 2.5, so this fix is relevant for 2.5 version.

Notes:

1. This same text is also displayed in the console plugin UI: https://github.com/kubev2v/forklift-console-plugin/blob/7ac736db94a33c1efe4ce26e6e[…]-console-plugin/locales/en/plugin__forklift-console-plugin.json

2. Going over this whole CLI doc section, it seems that openshift (and ova) as source providers are missing in other places where type is mentioned (e.g Provider manifest ), so maybe worth adding it as well.
