GDP - Provider Throwing an Error

Background

@rmcd @ahopkins1 and I encountered an issue when running the GDP container built from the current main branch. It seems like one (or possibly more) of the resources that use the xarray provider in pygeoapi are missing an epsg_code, causing the provider to fail in generating the openapi.yml file.

I think there are at least two components to this issue.

1. The xarray provider in pygeoapi should be updated to fail gracefully and issue/log a warning for this resource and then continue to the next one. That would make it easier to identify the data source that needs to be corrected, but also make it such that a single invalid datasets doesn't prevent the whole thing from building
2. We need to identify the invalid dataset(s) and add the missing epsg_code.

Closure Criteria

the pygeoapi fork and/or the gdp config has been updated to allow the container to initialize.
