@openhands-agent fix builds

[enyst]

@vinisdl Sorry, openhands-agent works only on branches from the repo and caller with permissions, it doesn't on external branches (a limitation because it's called from github actions).

An alternative is to set it up and run it on your forked repo, if you wish, or to run it locally (it has a headless entry point). Another alternative may be to use the @OpenHands tag, which works on the company cloud service.
