#### Overview of the Issue

According to https://developer.hashicorp.com/packer/integrations/hashicorp/oracle/latest/components/builder/oci#required-configuration-parameters base_image_filter string map can be used instead of base_image_ocid. However, doing this change results in below error.

```
$ packer validate -var-file="ms-oci-ol9-builder.pkrvars.hcl" ms-oci-ol9-builder.pkr.hcl
_Error: Unsupported argument

on ms-oci-ol9-builder.pkr.hcl line 30:
(source code not available)

An argument named "base_image_filter" is not expected here. Did you mean to
define a block of type "base_image_filter"?_
```

#### Reproduction Steps

Create packer file as below (some items redacted)

```
packer {
required_plugins {
oracle = {
version = ">= 1.0.4"
source = "github.com/hashicorp/oracle"
}
}
}

locals {
date_suffix = formatdate("YYYY-MM-DD", timestamp())
}

variable "os_shortname" {
type = string
}

variable "disk_size" {
type = number
default = 50
}

variable "repo_name" {
type = string
}

source "oracle-oci" "ms-oci-builder" {
availability_domain = "oxNh:US-ASHBURN-AD-1"
#base_image_ocid = "ocid1.image.oc1.iad.aaaaaaaa66oholjcnzscadxglrabahc5ygsjp5f764eofwdbivsz5zxyl2ja"
base_image_filter = {
"operating_system" = "Oracle Linux"
"operating_system_version" = "9.2"
"display_name_search" = "^Oracle-Linux-9.[0-9]-[0-9]+"
}
compartment_ocid = "ocid1.compartment.oc1................"
instance_name = "ms-oci-${var.os_shortname}-builder"
instance_tags = {
"deployed_by" = "ms_az_devops"
"reason" = "temporary image build environment"
}
disk_size = var.disk_size
image_compartment_ocid = "ocid1.compartment.oc1................................"
image_name = "ms-oci-${var.os_shortname}-${local.date_suffix}"
tags = {
"deployed_by" = "ms_az_devops"
"repo_name" = var.repo_name
}
shape = "VM.Standard1.1"
ssh_username = "opc"
subnet_ocid = "ocid1.subnet.oc1..........................."
key_file = "oci.pem"
use_private_ip = true
}

build {
name = "ms-oci-ol9-buider"
sources = ["source.oracle-oci.ms-oci-builder"]
}
```

with proper var file (not shown), run either of the below commands.

packer validate -var-file="ms-oci-ol9-builder.pkrvars.hcl" ms-oci-ol9-builder.pkr.hcl
packer build -var-file="ms-oci-ol9-builder.pkrvars.hcl" ms-oci-ol9-builder.pkr.hcl
