FCM handle Mint connection closed case

[mbarekTrismegistus]

I've runned into this error when i switched to the latest version that uses mint and not kadabra
it's basically straightforward, the closed connection case is not handled so im handling it

14:50:59.542 [error] GenServer #PID<0.2806.0> terminating Jul 11 14:50:59 instance-20250220-1457 zawajonlypheonix[2408916]: ** (MatchError) no match of right hand side value: {:error, %Mint.HTTP2{transport: Mint.Core.Transport.SSL, socket: {:sslsocket, {:gen_tcp, #Port<0.157>, :tls_connection, :undefined}, [#PID<0.2810.0>, #PID<0.2809.0>]}, mode: :active, hostname: "fcm.googleapis.com", port: 443, scheme: "https", authority: "fcm.googleapis.com", state: :closed, buffer: "", send_window_size: 1048576, receive_window_size: 16777216, receive_window_remaining: 16777216, receive_window_update_threshold: 160000, encode_table: %HPAX.Table{protocol_max_table_size: 4096, max_table_size: 4096, huffman_encoding: :never, entries: [], size: 0, length: 0, pending_minimum_resize: nil}, decode_table: %HPAX.Table{protocol_max_table_size: 4096, max_table_size: 4096, huffman_encoding: :never, entries: [], size: 0, length: 0, pending_minimum_resize: nil}, ping_queue: {[], []}, client_settings_queue: {[], []}, next_stream_id: 3, streams: %{}, open_client_stream_count: 0, open_server_stream_count: 0, reserved_server_stream_count: 0, ref_to_stream_id: %{}, server_settings: %{max_frame_size: 16384, initial_window_size: 1048576, max_concurrent_streams: 100, max_header_list_size: 65536, enable_connect_protocol: false, enable_push: true}, client_settings: %{max_frame_size: 16777215, initial_window_size: 2147483647, max_concurrent_streams: 100, max_header_list_size: 262144, enable_push: true}, headers_being_processed: nil, proxy_headers: [], private: %{}, log: false}, %Mint.HTTPError{reason: :closed, module: Mint.HTTP2}}

this is just my approach to make it work for my own use for now as for version 2.1 is not published yet, maybe this is fixed in the said version
