Option to not write "from_schema" slots in sheets2linkml rendered yaml about schemasheets

[cmungall]

There is a flag here, inject_metadata, default True:

https://github.com/linkml/linkml-runtime/blob/a1d2c0c728ed4d260869c877a033e2827e5173ef/linkml_runtime/utils/schemaview.py#L150-L183

But this may have some side effects if this is not stored - schemaview works with an import closure by default and the semantics of some slots may be relative to the containing schema; e.g:

https://github.com/linkml/linkml-runtime/blob/a1d2c0c728ed4d260869c877a033e2827e5173ef/linkml_runtime/utils/schemaview.py#L787

I think this should be redesigned such we don't rely on injection but instead on a separate map of (unique) elements to schemas; this is essentially what is done here: https://github.com/linkml/linkml-runtime/blob/a1d2c0c728ed4d260869c877a033e2827e5173ef/linkml_runtime/utils/schemaview.py#L781-L788

so I think we should be fine if we modify the logic here

But we will want lots more tests here

in the interim I would just add something here: https://github.com/linkml/linkml-runtime/blob/main/linkml_runtime/utils/schema_as_dict.py

You will likely want to use this anyway, to avoid the repetition of name as both a key and a slot

it looks like schema_as_dict is working now, @putmantime? closing for now; please reopen if this is still an issue?
