Fixing docs building problem

[isaacgsmith]

This pull request should fix issues that caused build errors in the documentation.

Description

File paths in symlinks and notebooks are changed to reflect the reorganization of the files in pull request #1379.

Motivation and Context

Following pull request #1379, the change in file paths and file names caused build errors in the documentation, as the notebooks did not function properly. Pull request #1382 fixed one of these problems, but due to technical problems on my end I was unable to test the rest of the notebooks locally when working on #1382 . This pull request fixes the remainder of the issues.

How Has This Been Tested?

After doing some troubleshooting in slack and with Andrew, I got the locally built the documentation successfully with all of the notebooks running correctly.

Screenshots (if appropriate):

Hi @smithis7

1. Your links are still broken :( To check which softlinks are not pointing to files use:

   find . -type l ! -exec test -e {} \; -print
   

   inside the docs/ folder.

   My advice to fix softlinks is: a) cd to the folder where the softlink lives b) make your changes c) go up to docs/ and use the
   above command to check if the new link worked. Remember the path you need to use is relative, so count how many times you need to go up doing ../.

2. Try to commit notebooks you modified in this PR with cleared output, otherwise the number of diff lines is too high on every PR.

3. Also I think there are more references to the old URL (that starting with raw.github...) you changed on your previous PR. Look for them!

Good work!
