google-analytics-data - received '13:Internal error encountered.' when running a report, and passing an incorrect shape in the `metrics` field

*edit: Issue is resolved, but leaving this open because this error isn't being handed on the Google side. Original below:*

Hi,

I'm working on porting a UA integration over to v4 / data v1, and and am running into this error for a very simple request. I've traced through the gem to ensure that the auth method is valid (which it should be, as `Google::Auth::UserRefreshCredentials` is a `Signet::OAuth2::Client`). Not sure what else it could be.

#### Environment details

- OS: Ubuntu 22.04.1
- Ruby version: 3.1.0
- Gem name and version: google-analytics-data v. 0.3.1

#### Steps to reproduce

1. The included script below (when filled with accurate parameters) shows the issue

#### Code example

```ruby
client_id = 'my-client-id'
client_secret = 'my-client-secret'
access_token = 'my-access-token'
refresh_token = 'my-refresh-token'
property_id = 'my-property-id'

client = ::Google::Analytics::Data.analytics_data do |config|
config.credentials = Google::Auth::UserRefreshCredentials.new(
client_id: client_id,
client_secret: client_secret,
access_token: access_token,
refresh_token: refresh_token,
scope: 'https://www.googleapis.com/auth/analytics.readonly',
expires_at: 0
)
end

report = {
property: "properties/#{property_id}",
date_ranges: [{ start_date: '2022-08-03', end_date: '2022-08-10' }],
metrics: [{ name: 'gametric', expression: 'active28DayUsers' }],
dimensions: [{ name: 'date' }]
}

client.run_report(report)
```

Start with the analytics data client's run_report entry point and reproduce the request shown in the issue, including the metrics shape. Determine whether this malformed request is within the Ruby client’s scope or is handled only by Google’s service; the issue is complete only when the expected error behavior is defined and covered by a regression test.
