Mongo validation toolkit: Implement LinkML-based validation routine

[eecavanna]

As part of creating a toolkit developers can use to validate the contents of the NMDC Mongo database...

Implement a function(s) that developers can use to perform LinkML-based validation of data in (or retrieved from) the NMDC Mongo database.

Notes:

• The nmdc-schema Python package includes a LinkML YAML representation of the NMDC schema
• The LinkML documentation contains an example of performing validation via the CLI (although the default behavior performs JSON Schema-based validation under the hood)

This task originated as a subtask of https://github.com/microbiomedata/issues/issues/266.

I am under the impression both JSON Schema-based, and LinkML-based validation, are necessary in order to fully validate NMDC Mongo data; but it is not clear to me what LinkML-based validation is, given that the default behavior of the linkml-validate command performs JSON Schema-based validation under the hood.

Edit: Based on what I see in the LinkML documentation about a different command, it looks to me like it may involve using Python DataClass-based validation.
