allow the `Grafana Assume Role` feature for `grafana-amazonprometheus-datasource`

[imankurpatel000]

Is your feature request related to a problem? Please describe.
We should allow the Grafana Assume Role feature for grafana-amazonprometheus-datasource. Currently, we are only allowing this feature for cloudwatch and grafana-athena-datasource here.

Describe the solution you'd like
Add grafana-amazonprometheus-datasource to this array so we can use Grafana Assume Role feature with this datasource as well.

Hi @imankurpatel000, thanks for showing interest for this feature! We have some preparation work to do before we enable it in the sdk, but I will add this request along with others for Amazon Prometheus in our backlog and we hope to get to it soon.
