Ask LinkML team to add a prefix

@cmungall @sierra-moxon @caufieldjh does LinkML have its own namespace? Where can I find that? @LucaCappelletti94 gave me a summary of stuff the Bioregistry couldn't parse over KGOBO that included the following node names:

1 linkml:values_from
1 linkml:value_description
1 linkml:value
1 linkml:type_uri
1 linkml:status
1 linkml:see_also
1 linkml:required
1 linkml:recommended
1 linkml:permissible_values
1 linkml:pattern
1 linkml:name
1 linkml:multivalued
1 linkml:minimum_value
1 linkml:meaning
1 linkml:maximum_value
1 linkml:local_names
1 linkml:local_name_value
1 linkml:local_name_source
1 linkml:imported_from
1 linkml:identifier
1 linkml:from_schema
1 linkml:examples
1 linkml:exact_mappings
1 linkml:description
