`opm alpha render-template` doesn't recognize schema in v1.62.0

I'm getting:

$ opm alpha render-template basic
Error: creating template by type: unknown template schema: basic

In the code, it looks like GetSupportedTypes() is returning the last portion of the schema:

operator-registry/alpha/template/registry.go

Line 121 in 783862a

types = append(types, schema[strings.LastIndex(schema, ".")+1:])

But then the factory is just returning the schema, which is the full path rather than just the last portion:

operator-registry/alpha/template/registry.go

Line 68 in 783862a

r.factories[factory.Schema()] = factory

operator-registry/alpha/template/basic/basic.go

Line 16 in 783862a

const schema string = "olm.template.basic"

So then GetTemplateByType() is trying to index by the full path, which doesn't match the shorter type:

operator-registry/alpha/template/registry.go

Line 81 in 783862a

factory, exists := r.factories[schema]

Perhaps this PR introduced the regression?
