Add support for expr_options field

[tknodell-recurly]

Google provider recently fixed bug that caused all rules to be recreated - hashicorp/terraform-provider-google-beta#8622

That seems to work fine. However this module still wants to recreate all rules to remove all expr_options which look to be added automatically

For example our plan shows

It will delete this rule

      - rule {
          - action      = "deny(403)" -> null
          - description = "Node JS attack" -> null
          - preview     = true -> null
          - priority    = 10 -> null

          - match {
              - expr {
                  - expression = "evaluatePreconfiguredWaf('nodejs-v33-stable', {'sensitivity': 4})" -> null
                }
              - expr_options {
                  - recaptcha_options {
                      - action_token_site_keys  = [] -> null
                      - session_token_site_keys = [] -> null
                    }
                }
            }
        }

And replace it with

      + rule {
          + action      = "deny(403)"
          + description = "Node JS attack"
          + preview     = true
          + priority    = 10

          + match {
              + expr {
                  + expression = "evaluatePreconfiguredWaf('nodejs-v33-stable', {'sensitivity': 4})"
                }
            }
        }

These are essentially the same
Can we add support for expr_options fields? Or ignore them so these dont get recreated every time
This only seems to affect the pre_configured_rules rule type

Have the same issue. Just fixed the perma diff upgrading google-beta provider to v6.11.1 but have been caught by this expr_options. I my case affects "custom_rules".

@tknodell-recurly according to the documentation expr_options is an optional variable. Issue #18596 was created for it. Seems like they fixed preconfigured_waf_config issue but they havnt fixed recaptcha_options.
I will test and add expr_options to the module.
