Suggestion Provider Fix

A minor change to Minecraft's suggestion provider so that it auto-completes resource locations for all mod namespaces. Whilst this is a very tiny change, if you use commands a lot in modded it is likely to save you a lot of time. Note that this mod does not need to be installed on a dedicated server to work, though doing so is advisable so that the client and server mod list match. ## Usage example Let's say you want to use `/give` to spawn yourself an `oak_seed` from Dynamic Trees. With vanilla, you may begin to type `/give @p oak_seed`. However, no auto-complete suggestions come up, as it expects you to type the fully qualified `dynamictrees:oak_seed` name:  When Suggestion Provider Fix is installed, beginning to type `oak_seed` will suggest any items with that name, regardless of which mod adds it. So, the oak seed from Dynamic Trees will be suggested:  This also works with other registries that use resource locations, including blocks, biomes, and even custom registries from other mods. ## Licensing Permission is hereby granted to use this mod in ANY mod pack or server. Attribution would be nice but isn't required. ## Technical description This mod uses a Mixin to overwrite `SharedSuggestionProvider#filterResources(Iterable, String, Function, Consumer)`, doing exactly the same thing but negating a check on whether or not the namespace of the `ResourceLocation` is equal to `minecraft` (since this is the default when a path is typed without a namespace). This means that suggestion providers for `ResourceLocation` objects will suggest all paths matching the input string if no namespace was entered, instead of only those from Minecraft itself.
