Feature Request: Get Guild Role

[SinisterRectus]

Guild roles are always provided in the guild's roles arrays and they are kept current by GUILD_ROLE_* events. With a fully operational gateway connection, there is rarely a need to fetch roles via HTTP. However, after the introduction of intents and stateless client behaviors, it is more likely that objects may become stale and need to be re-fetched via HTTP. With this in mind, I'd like to request that a "Get Guild Role" endpoint be added for fetching individual roles by ID, consistent with how other objects (emojis, bans, members, etc) may be fetched by ID via HTTP.
