Verify all agents for all sims working

[ShvetankPrakash]

It appears many agents are not working out of the box. We should verify all of them and add the necessary documentation,

For example:

$ python train_randomwalker_DRAMSys.py 
Traceback (most recent call last):
  File "/home/oss-arch-gym/sims/DRAM/train_randomwalker_DRAMSys.py", line 11, in <module>
    from arch_gym.envs import dramsys_wrapper
  File "/home/oss-arch-gym/arch_gym/envs/dramsys_wrapper.py", line 19, in <module>
    from acme import specs
ImportError: cannot import name 'specs' from 'acme' (unknown location)

We need to add something like os.sys.path.insert(0, os.path.abspath('../../acme')) like in train_ppo.py under sims/DRAM

Noting here that @manan-garg1504 is working with @aadyapipersenia04 to add acme to install script for this issue

@AditiR-42 I was trying to run astra-sim after a clean install, but now the submodule cloning fails:

$ git submodule update --init --recursive  sims/AstraSim/astrasim-archgym
fatal: remote error: upload-pack: not our ref 53574d2f1d20e26d5143eb0ff0c98b6af338da61
fatal: Fetched in submodule path 'sims/AstraSim/astrasim-archgym', but it did not contain 53574d2f1d20e26d5143eb0ff0c98b6af338da61. Direct fetching of that commit failed.

Does the documentation need to be updated?

Thanks for working on this @manan-garg1504 ! @AditiR-42 @jared-ni can you help him resolve the issue. We want AstraSim working out of the box for the conference this week :)
