increase asdf version, switch _force_raw_types for load_yaml

[braingram]

Increases minimum asdf version to 3.1.0 (inline with jwst: https://github.com/spacetelescope/jwst/blob/master/pyproject.toml#L22) and switches _force_raw_types usage to load_tree.

Also updates one test that fails with ASDF standard 1.6.0 as the default due to an incorrect assumption about the tag version:

stdatamodels/src/stdatamodels/jwst/transforms/converters/tests/test_models.py

Lines 76 to 77 in 50751a8

	with asdf.open(path, _force_raw_types=True) as af:
	assert af.tree["model"]._tag == "tag:stsci.edu:jwst_pipeline/niriss_soss-1.0.0"

assumes the tag will be 1.0.0. With ASDF standard 1.6.0 the tag will be 1.1.0:

stdatamodels/src/stdatamodels/jwst/transforms/resources/manifests/jwst_transforms-1.1.0.yaml

Lines 46 to 47 in 50751a8

	- tag_uri: "tag:stsci.edu:jwst_pipeline/niriss_soss-1.1.0"
	schema_uri: http://stsci.edu/schemas/jwst_pipeline/niriss_soss-1.1.0

Approve the minimum asdf bump - but I don't quite follow the change from _force_raw_types to load_yaml. Does this address a bug, improve performance, prep for a deprecation, or something else entirely?

[braingram]

Thanks for taking a look. I should have added more details.

asdf-format/asdf#1700 introduced load_yaml to try and replace the (many) uses of the private argument _force_raw_types. It was included in asdf 3.1.0 and since jwst increased the minimum version we can follow suit with this PR and swap out all the uses. So sort of dealing with a deprecation as now asdf can consider removing that private argument to clean up asdf.open.

Looks good, appreciate the clarification! Sorry for the accidental re-request, @zacharyburnett - misclick 😬
