CI: suppress npdev warnings
Let's try this again
great! we see errors on 1.2.x. let's see is this backports.

@meeseeksdev backport 1.2.x Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

```
$ git checkout 1.2.x
$ git pull
```

2. Cherry pick the first parent branch of the this PR on top of the older branch:
```
$ git cherry-pick -m1 505abc1c2617561e80d6926bc48bf4275fd6815c
```

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

```
$ git commit -am 'Backport PR #41730: CI: suppress npdev warnings'
```

4. Push to a named branch :

```
git push YOURFORK 1.2.x:auto-backport-of-pr-41730-on-1.2.x
```

5. Create a PR against branch 1.2.x, I would have named this PR:

> "Backport PR #41730 on branch 1.2.x"

And apply the correct labels and milestones.

Congratulation you did some good work ! Hopefully your backport PR will be tested by the continuous integration and merged soon!
