[enhancement] Custom provider page - Change controlPlane provider type

[cpinjani]

Setup Rancher version: v2.8-head Rancher Turtles: v0.6.0 Rancher UI Extensions: CAPI UI Extension v0.4.0 Browser type & version: Chrome Latest

To Reproduce

• Install CAPI UI extension
• Open Cluster Management > CAPI Menu
• Open Infrastructure Providers > Create > Custom

Expected Result Provider type drop-down has values - infrastructure, bootstrap, controlPlane. Would be good to controlPlane to control-plane It would align with other provider names/values which are not camel case, eg. cluster-api, rke2-bootstrap, etc.
