prs_created is false when a release PR is updated

### TL;DR


says it will set prs_created to true when it updates a pr.

but it doesn't.

### Expected behavior

if a release pr is updated, set `prs_created` to `true`.

### Observed behavior

if a release pr is updated, set `prs_created` to `false`.
