[Proposal] Simplify the registered environments

[pseudo-rnd-thoughts]

ALE has never followed the version standard of Gym or Gymnasium with v0 and v4 affecting various parameters

Version	frameskip=	repeat_action_probability=	full_action_space=
v0	(2, 5,)	0.25	False
v4	(2, 5,)	0.0	False
v5	5	0.25	False

Additionally, for every ROM there are 14 environments registered

Name	obs_type=	frameskip=	repeat_action_probability=
Amidar-v0	"rgb"	(2, 5,)	0.25
AmidarDeterministic-v0	"rgb"	4	0.0
AmidarNoframeskip-v0	"rgb"	1	0.25
Amidar-ram-v0	"ram"	(2, 5,)	0.25
Amidar-ramDeterministic-v0	"ram"	4	0.0
Amidar-ramNoframeskip-v0	"ram"	1	0.25
Amidar-v4	"rgb"	(2, 5,)	0.25
AmidarDeterministic-v4	"rgb"	4	0.0
AmidarNoframeskip-v4	"rgb"	1	0.25
Amidar-ram-v4	"ram"	(2, 5,)	0.25
Amidar-ramDeterministic-v4	"ram"	4	0.0
Amidar-ramNoframeskip-v4	"ram"	1	0.25
ALE/Amidar-v5	"rgb"	5	0.25
ALE/Amidar-ram-v5	"ram"	5	0.25

This results in ALE registering 960 environments, of which 372 for v0, 372 for v4 and 216 for v5
Of which 480 is just RAM environments

In my honest opinion, this is mad

We should be able to have a single environment, ALE/Amidar-v5 with users changing parameters as necessary
Additionally, this would allow us to update the environment version if bugs/changes are made

If this change is made, we could do it at v1.0
