Discord templates do not import forum channels and announcement channels

Reproduction steps

Own a discord server with at least one announcement channel and/or forum channel
Create a server template
On Fluxer, Click the "Create or Join Community" button
Import Discord Template
Paste your template url (e.g. https://discord.new/12345)
(Desktop only) Paste the JSON into the form. On mobile this is skipped somehow.
Click Next
Click Create Community

Expected behaviour

All channels should get imported regardless of type (except maybe Stage channels since we don't have those, but maybe those could be imported as basic voice channels?)

Actual behaviour

Only text and voice channels are imported. Forum channels and announcement channels get skipped.
