Refactor usages of blacklist and whitelist

[jdrueckert]

Motivation

Whitelist and blacklist are nowadays referred to using the more inclusive terms allowlist and denylist (or blocklist).
Due to the age and size of our codebase, in older parts of the code we still use the less inclusive terms, e.g. in (ServerConnectListManager.java)[https://github.com/MovingBlocks/Terasology/blob/develop/engine/src/main/java/org/terasology/engine/network/internal/ServerConnectListManager.java]
We want to demonstrate our openness and inclusiveness not only in how we treat people but also in our code, so this should be changed.

Proposal

Search our codebase for usages of "whitelist" and "blacklist" and refactor these usages to "allowlist" and "denylist".

@fakegithub01 uh, interesting user name there, and now I'm starting to wonder if this issue is getting bot-attention, rather than any serious reading.
