chore: add dataloader to release-please manifest and fix mongoose

[rauno56]

Which problem is this PR solving?

We forgot to add instrumentation-dataloader to the manifest and instrumentation-mongoose had a wrong path.

I'm still confused about which files need to be touched to keep release please happy. I thought that .release-please-manifest.json is updated by release please and users have to add their module only in release-please-config.json?

I feel you. I'm constantly confused myself as well.

Adding packages to manifest is only important because we don't release 1.0.0 as the first version. In my mind:

• manifest -> release please's state;
• config -> our preferences for release please.
