[docs]: Perhaps remove page E4S

Please describe the issue

@sameershende @eugeneswalker

I had documented this page https://e4s.readthedocs.io/en/latest/spack.html but it looks like this is already out of date and considering we have lots of spack configuration. I think if we are not going to document every release in this page i would vote for removing this page. This page showed the spack configuration in readthedocs in rendered form so it was somewhat convenient if one is reading the docs and sees the spack configuration

I don't think keeping this up to date will be terribly onerous. It hasn't been on my radar though. I'd like some more feedback on if we should maintain or remove it before I proceed.

To help ensure that we keep documentation like this up to date, it might be a good idea to create a release procedure checklist that lists what pages need to be updated when new releases of E4S come out. That way we don't forget about something.

That's a good idea @nchaimov

This should be updated https://e4s.readthedocs.io/en/latest/introduction.html#references

I wrote this up a while back so we can put references in the docs.

Anyway I recommend that you all should read and get familiar with the docs and what's written so it can be improved.
