Experimental camera presets are no longer available

Steps to Reproduce:

1. Turn on the "Experimental Cameras" toggle in a world;
2. Try to use the /camera command.

Observed Results:
Only "minecraft:first_person", "minecraft:third_person" and "minecraft:third_person_front" are available.

Expected Results:
All presets can be used. Previous versions would include "minecraft:free", as well as some example ones.

Screenshots/Videos attached: Yes

Notes: This severely hinders the use of this command on unmodified creative worlds.
