Allow overriding the "isDevelopment" value.

[Mickey42302]

I would like to suggest adding a feature which can be used to override the "isDevelopment" value that is built into vanilla Minecraft (it is located within the SharedConstants class). This value controls whether or not the code for the game's hidden development features will be activated. One example is the code which allows some of the debug renderers to function on servers. The debug renderers and other development features (such as the "/chase" command) can be accessed by a client through the use of mods (https://github.com/Mickey42302/JavaEditionDevTools). However, if the "isDevelopment" value returns false, the server will not enable the code that allows some of the debug renderers to show the information they are designed to provide.

By allowing users to override this value, the community will be able to explore the tools used by Mojang/Microsoft to develop the game while still being able to enjoy the functionalities offered by Purpur/plugins.

As far as I know some stuff from debug stuff isn't in the public build

[Mickey42302]

That is the case for some features (such as the WireFrame key combination). However, there is still a lot of debugging code that is functional.

For example, the pathfinding debug renderer can be used to see pathfinding data for mobs, including data that is generated with the "/debugpath" command (https://www.youtube.com/watch?v=9g2WI6V-W_A). However, the code which sends the required information to the debug renderer does not function unless the "isDevelopment" value returns true.
