fix(resources): wait for async attributes for detecting resources

[ziolekjj]

Which problem is this PR solving?

Recently, HostDetector was added as default for detectors in NodeSDK, this produces the error message: Accessing resource attributes before async attributes settled, as detectResourcesSync is not waiting for async attributes to be resolved for HostDetector, what causes the lack of machine_id passed to it.

Fixes #4638

Short description of the changes

I've updated the test case for the issue and added an await statement to wait for async attributes to be resolved for the detectResourcesSync function.

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

I've added unit tests, the configuration for reproducing is described in the linked issue #4638

• Updated a test to detect-resources.test.ts to reflect the behavior of the HostDetector with async attributes

I've tested the change locally. It solved the issue, the message is not logged and host.id is present on spans 👌

Hey @pichlermarc, sorry for mentioning you; I'm not sure who would be the best person to ask for a review here, It still requires a code owner approval, is everything good here? I am happy to help with pushing this forward
