atari100k config should use task "atari100k_pong" instead of "atari_pong"

[rsun0]

In dreamerv3/configs.yaml, the atari100k example config uses the task "atari_pong"

dreamerv3/dreamerv3/configs.yaml

Lines 170 to 172 in 55c8c67

	atari100k:
	task: atari_pong
	run: {steps: 1.1e5, envs: 1, train_ratio: 256}

However, the first part of the task name is the "suite" which is used to select the env:

dreamerv3/dreamerv3/main.py

Lines 212 to 213 in 55c8c67

	def make_env(config, index, **overrides):
	suite, task = config.task.split('_', 1)

dreamerv3/dreamerv3/main.py

Line 239 in 55c8c67

kwargs = config.env.get(suite, {})

The correct suite should be "atari100k" so the task name should be "atari100k_pong". Otherwise, the atari (Atari 200M) env config will be used instead:

dreamerv3/dreamerv3/configs.yaml

Lines 29 to 33 in 55c8c67

	env:
	atari: {size: [96, 96], repeat: 4, sticky: True, gray: True, actions: all, lives: unused, noops: 30, autostart: False, pooling: 2, aggregate: max, resize: pillow, clip_reward: False}
	procgen: {size: [96, 96], resize: pillow}
	crafter: {size: [64, 64], logs: False}
	atari100k: {size: [64, 64], repeat: 4, sticky: False, gray: False, actions: needed, lives: unused, noops: 30, autostart: False, resize: pillow, clip_reward: False}
