Page schema: `entity` is not a valid value for `type` attribute in page resource.

[danigrb]

Hi, when trying to import and manage entity pages (the ones which detail the entity, for example this page) using this provider we can successfully import the resource, but subsequent plans fail validation because entity is not a valid type.

 Error: Invalid Attribute Value Match
│ 
│   with port_page._userEntity,
│   on port_page__userEntity.tf line 7, in resource "port_page" "_userEntity":
│    7:   type        = "entity"
│ 
│ Attribute type value must be one of: ["blueprint-entities" "dashboard" "home"], got: "entity"

My understanding is that this validator:

terraform-provider-port-labs/port/page/schema.go

Lines 29 to 32 in 4016746

	stringvalidator.OneOf(
	"blueprint-entities",
	"dashboard",
	"home",

Should also include entity value, as it is a valid value for type in page.

Thank you!
