Update text for gender_source_value in the CDM

CDM or THEMIS convention?

CDM

Is this a general convention?

No

Summary of issues

• The current text states to "put the biological sex of the person as it appears in the source data" this wording can be problematic because it does not align with the guidance for gender_concept_id

Summary of answer

• Update this text to say. "put the assigned sex at birth of the person as it appears in the source data"

Note to builders - this is a CDM convention so it needs to be updated in the CDM docs, not the THEMIS repo
