Suggestion to allow policy

[navin0812]

Hi,
I just started to use this module. But for our use case, other than lambda lambda:UpdateFunctionCode we are using several other policies as well. I'd like to make a suggestion to include role_policy_arns so that we can attach that policy to it.

module "lamda_gha" {
  source  = "philips-labs/github-oidc/aws"
  version = "~> 0.7.0"

  count = var.create_github_actions_role ? 1 : 0

  openid_connect_provider_arn = var.create_github_actions_oidc_provider ? module.oidc_provider[0].openid_connect_provider.arn : data.aws_iam_openid_connect_provider.github.arn
  repo                        = var.github_repo.repo
  role_name                   = var.github_repo.role_name
  github_environments         = var.github_repo.environments
  
  + role_policy_arns =  var.attach_policy ? [var.role_policy_arns] : []
  
  default_conditions = var.default_conditions

  conditions = length(var.github_repo.branches) != 0 ? [
    {
      test     = "StringLike"
      variable = "token.actions.githubusercontent.com:sub"
      values   = [for branch in var.github_repo.branches : "repo:${var.github_repo.repo}:ref:refs/heads/${branch}"]
    },
  ] : []
}
