Misleading documentation about using RegEx in gcp_compute_forwarding_rule_info filter

Hi,

My goal was to filter forwarding rules using RegEx. I got familiar with:
https://docs.ansible.com/ansible/latest/collections/google/cloud/gcp_compute_forwarding_rule_info_module.html#parameter-filters
It directed me to https://cloud.google.com/sdk/gcloud/reference/topic/filters

I tried to use a RegEx based filter like that (using ~ operator as it was indicated in https://cloud.google.com/sdk/gcloud/reference/topic/filters):

```
gcp_compute_forwarding_rule_info:
filters:
- "name ~ 'test.+'"
```

However, GCP returned an error. At the same time I was able to use mentioned filter with gcloud. After some digging I realized that gcp_compute_forwarding_rule_info module talks to https://cloud.google.com/compute/docs/reference/rest/v1/forwardingRules/list service. In order to use RegEx I had to change my declaration to:

```
gcp_compute_forwarding_rule_info:
filters:
- "name eq test.+" # Google RE2 syntax
```
Please correct the documentation because I had to spend a couple of hours to find a way to use RegEx. Please verify if this problem is gcp_compute_forwarding_rule_info related only.

Start with the gcp_compute_forwarding_rule_info documentation for the filters parameter, then compare its linked gcloud filter reference with the Compute Engine forwardingRules.list reference. Verify whether the documented regular-expression syntax applies only to this module or to other related modules, and update the documentation to describe the working syntax and distinction.
