Currently, Special:SetSchemaLabelDescriptionAliases uses the` MonolingualSchemaData` value-object to get the data, including the Schema text and it writes the Data with MediaWikiRevisionSchemaWriter::updateSchema method, also including the Schema text. However, since the Schema text is not supposed to be edited, this is unnecessary and should be removed.

Acceptance criteria

• The data from the special page is saved using MediaWikiRevisionSchemaWriter::updateSchemaNameBadge
• The special page does not include a field for the Schema text (hidden or otherwise)
• The data is retrieved from the SchemaDispatcher in a way that does not include the Schema text
