[ISSUE][DOCS] Deprecated Alias @assets@

[PHandradee]

Describe the issue

I believe the documentation page File IO - List of Aliases need to be updated, particularly focusing on "The Aliasing System".
I tested the code shown on this page, and here are my findings:
Deprecated warning using @assets@

CustomReadJsonFile("@products@/assets/skillsdb.json");
...       
        AZ::IO::HandleType fileHandle = AZ::IO::InvalidHandle;
        AZ::IO::FileIOBase* fileIO = AZ::IO::FileIOBase::GetInstance();
        AZ_Printf("FileContent", "@assets@ alias path: %s", fileIO->GetAlias("@assets@"));
        AZ_Printf("FileContent", "@products@ alias path: %s", fileIO->GetAlias("@products@"));
...

<12:38:32> [Error] (FileIO) - Alias "@assets@" is deprecated. Please use alias "@products@" instead
<12:38:32> (FileContent) - @assets@ alias path: D:\O3DE-Projects\Projects\ProjectM\Cache\pc
<12:38:32> (FileContent) - @products@ alias path: D:\O3DE-Projects\Projects\ProjectM\Cache\pc

Another good addition would be::
How to get all the available Aliases?

Impacted page(s)

File IO - List of Aliases

Expected experience

Expected to have the updated information and the complete list of aliases.
