release: 0.9.3 (#79)

### Description

This release removes the `pagerDuty.apiToken` and `pagerDuty.oauth`
configuration definitions from this repository as they should be treated
as secret config and this frontend plugin does not need to know about
them.

These configurations will now be exclusive to the backend plugin.
