yarn tsc failing on orchestrator-backend on the main branch

[rm3l]

Describe the bug

I rebased my PR (#1471) onto main, and noticed some failures due to recent changes in the orchestrator-backend.

I checked main and noticed that yarn tsc also errors out.

https://github.com/janus-idp/backstage-plugins/actions/runs/9698241417/job/26765971595

Expected Behavior

yarn tsc should pass with no error.

What are the steps to reproduce this bug?

$ yarn workspace @janus-idp/backstage-plugin-orchestrator-backend tsc

yarn workspace v1.22.20
yarn run v1.22.20
$ tsc
src/service/router.ts:1178:31 - error TS2304: Cannot find name 'JiraEvent'.
