Compression Rulesets don't yet support zstandard algorithm

Confirmation

• This is a bug with an existing resource and is not a feature request or enhancement. Feature requests should be submitted with Cloudflare Support or your account team.
• I have searched the issue tracker and my issue isn't already found.
• I have replicated my issue using the latest version of the provider and it is still present.

Terraform and Cloudflare provider version

Terraform v1.8.5
on darwin_arm64
+ provider registry.terraform.io/cloudflare/cloudflare v4.43.0

Your version of Terraform is out of date! The latest version
is 1.9.5. You can update by downloading from https://www.terraform.io/downloads.html

1.8.5 vs 1.9.5 for terraform version shouldn't really matter.

Affected resource(s)

cloudflare_ruleset

Terraform configuration files

resource "cloudflare_ruleset" "compression_rules" {
  zone_id     = var.zone_id
  name        = "Compression Settings"
  description = "Compression Settings"
  kind        = "zone"
  phase       = "http_response_compression"
  rules {
    action = "compress_response"
    action_parameters {
      algorithms {
        name = "zstandard"
      }
      algorithms {
        name = "auto"
      }
    }
    expression  = "(http.response.content_type.media_type in {\"text/html\"})" # or any other expression
    description = "Zstandard"
    enabled     = true
  }
}

Link to debug output

Probably not necessary here

Panic output

No response

Expected output

It should accept zstandard here.

Actual output

terraform validate
│ Error: Invalid Attribute Value Match
│
│   with cloudflare_ruleset.compression_rules,
│   on rules-compression.tf line 11, in resource "cloudflare_ruleset" "compression_rules":
│   11:         name = "zstandard"
│
│ Attribute rules[0].action_parameters[0].algorithms[0].name value must be one of: ["gzip" "brotli" "auto" "default" "none"], got: "zstandard"

Steps to reproduce

1. Using 4.43.0 of terraform
2. Create a cloudflare_ruleset object for compression rules, and specify zstandard as the algorithm
3. Receive error

Additional factoids

I'm happy to make the PR to fix it :)

Thank you for reporting this issue! For maintainers to dig into issues it is required that all issues include the entirety of TF_LOG=DEBUG output to be provided. The only parts that should be redacted are your user credentials in the X-Auth-Key, X-Auth-Email and Authorization HTTP headers. Details such as zone or account identifiers are not considered sensitive but can be redacted if you are very cautious. This log file provides additional context from Terraform, the provider and the Cloudflare API that helps in debugging issues. Without it, maintainers are very limited in what they can do and may hamper diagnosis efforts.

This issue has been marked with triage/needs-information and is unlikely to receive maintainer attention until the log file is provided making this a complete bug report.
