Fix NPE when calling NettyHeadersAdapter.add()

Browse Source 
Prior to this commit, the `NettyHeadersAdapter` would directly delegate
the `add()` and `set()` calls to the adapted
`io.netty.handler.codec.http.HttpHeaders`. This implementation rejects
`null` values with exceptions.

This commit aligns the behavior here with other implementations, by not
rejecting null values but simply ignoring them.

Fixes gh-26274
