Update aliases to reflect package name

[jessegrabowski]

Description

This PR changes all the aliases in all the code from at, aes, aer, etc., to pt, ps, ptr, etc. This includes in tests, docs, and the main codebase.

Also I directly changed the .rst files in the docs, I'm not sure if I was supposed to do that, or if those are auto-generated?

There's many more import pytensor.tensor as at in the codebase. Do you want to fix it or remove the one test file you changed? Otherwise it's a bit odd (but not a big deal). That touches on #380

[jessegrabowski]

I'll just do it all what the heck.

Unless you want it in a different PR. If so I'll revert the one test file I got and open another one later to handle the codebase itself.
