Bug: Header name is always blank

[dta5003]

When attempting to define a header parameter like

    headerAccountId:
      name: accountId
      in: header
      required: true
      schema:
        type: string

the name of the header should be "accountId" but is generated as "".

Looks like the bug is here: https://github.com/darkpatternsdigital/openapi-generators/blob/04ee5fcb9b1c758c263d7aa8c20526ed1b07da6a/generators/csharp/OpenApiCodegen.CSharp.Base/Client/Templates/client.handlebars#L67C43-L67C51

{{BaseName}} should instead be {{RawName}}
