Why does this PR exist?

👀 Original community thread: https://tokens-studio.slack.com/archives/C02DLQXNY6Q/p1724944973329479

When users were pushing to GitLab, an error saying "Push to remote cancelled!" appeared on the modal, although it all works as expected.

What does this pull request do?

For GitLab & ADO, pushing to remote will actually fail, not showing this falsy error.

Testing this change

• Edit details in GitLab / ADO as a provider
• Follow the push to remote flow
• See successful edits in remote OR see error if you cancel the flow

✅ SUCCESS

❌ ERROR
