Support default_labels in MaterialRun constructor

This PR adds support for a new optional default_labels: List[str] parameter in the MaterialRun constructor.

Default labels are used to:

• Populate labels on the ingredient run, if none are explicitly specified, when the material run is later used as an ingredient
• Marking the material run as a potential replacement ingredient for a particular label when generating new candidates using a design space. Note that during design, default labels are only applicable if the material run has no associated ingredient run within the training set in question.

PR Type:

• Breaking change (fix or feature that would cause existing functionality to change)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Maintenance (non-breaking change to assist developers)

Adherence to team decisions

• I have added tests for 100% coverage
• I have written Numpy-style docstrings for every method and class.
• I have communicated the downstream consequences of the PR to others.
• I have bumped the version in __version__.py

Why is this being update here and not in https://github.com/CitrineInformatics/gemd-python/blob/main/gemd/entity/template/material_template.py? Nominally, that's where the data structure is inherited from.

This seemed to be the most directly equivalent to the logic that was added in https://github.com/CitrineInformatics/platform-backend/pull/5021 to support the design-over-untested-ingredients functionality via UI ingest -- adding the generated tags to the material run.

Since we don't add tags to the material template in that workflow I think it probably makes sense to limit the scope of this change as well, but I'm open to reconsidering.

This is fit for purpose. Some stylistic feedback to be provided off-line.

LGTM. Thanks for the additional tests.
