feat: add service_account_token resource

[srevinsaju]

• adds a new resource doppler_service_account_token
• added example usage
• autogenerated docs for newly added resource

Sample deployment

terraform {
  required_providers {
    doppler = {
      source = "doppler.com/core/doppler"
      version = "0.0.1"
    }
  }
}

provider "doppler" {
  doppler_token = "..."
}

resource "doppler_service_account" "ci" {
  name = "ci"
  workplace_role = "no_access"
}

resource "doppler_service_account_token" "builder_ci_token" {
  service_account_slug = doppler_service_account.ci.slug
  name            = "Builder CI Token"
  expires_at      = "2024-05-30T11:00:00.000Z"
}

output "service_account_token_slug" {
  value = doppler_service_account_token.builder_ci_token.slug
}

output "service_account_token_api_key" {
  sensitive = true
  value = doppler_service_account_token.builder_ci_token.api_key
}

What is tested:

• Creation (with expiry date)
• Creation (without expiry date)
• Update from no expiry date to having an expiry date, and vice versa - which should do a full CRUD test

Thanks so much for your submission, @srevinsaju! This works great from my local testing. I left a few minor comments with recommended patches.

If you aren't familiar, you can apply any of the patches by copying their contents and pasting (or piping) into git apply.
