Merge comments in YAMLs

[Mapacheee]

this PR improves the configuration system by adding support for comments. By default, the winterframework uses SpongePowered Configurate (SnakeYAML), but it doesnt support preserving comments during loads/saves.
to fix this, we now use a custom YamlCommentWriter to handle configuration updates while keeping comments intact!!!

If you have this:

  far-players:
    # Update interval for far-player movement packets.
    move-ticks: 4
    # Update interval for far-player equipment/metadata packets.
    equip-ticks: 20

and you will add a new config:

  far-players:
    # another comment
    test: 20

the final file will be:

  far-players:
    # Update interval for far-player movement packets.
    move-ticks: 4
    # Update interval for far-player equipment/metadata packets.
    equip-ticks: 20
    # another comment
    test: 20
