Cannot add repositories from Forgejo

Kubero UI

Describe the bug

When attempting to add a repository that is hosted on Forgejo, creation of the webook fails due to what I think is an inconsistency between Gitea and Forgejo's API. Specifically, the insecure_ssl value is undefined. Probably null coalescing to false will fix it.

Stack trace:

TypeError: Cannot read properties of undefined (reading 'insecure_ssl')
    at GiteaApi.addWebhook (/app/server/git/gitea.js:145:47)
    at process.processTicksAndRejections (node:internal/process/task_queues:105:5)
    at async GiteaApi.connectRepo (/app/server/git/repo.js:109:23)
    at async /app/server/routes/repo.js:29:15

Steps to reproduce

1. Go to create new pipeline.
2. Enable build from source.
3. Pick a gitea repo.
4. Press connect.

Expected behavior

No error. Repo connects.

I'll check this in v3. This might still be an issue there since these code parts where reused.
