refactor: rename Error to DiscordjsError internally

[almeidx]

Please describe the changes this PR makes and why it should be merged:
Renamed the Error, TypeError, and RangeError internally to DiscordjsError, DiscordjsTypeError, and DiscordjsRangeError. They were already being exported under this name

Hopefully prevents issues like these to not happen again:

• fix: Throw discord.js errors correctly #8697

Status and versioning classification:

• I know how to update typings and have done so, or typings don't need updating
