Update and rename CSOM methods for applying retention labels.md to csom-methods-for-applying-retention-labels.md

Please see changes in this commit for things I needed to implement to get this doc inline with MSDocs standards. Some of these things were reported in the automated build checks added to the PR, including:

- can't use absolute URLs to things that are relative
- incorrect use of NOTE (putting it on it's own line in a block quote, like the IMPORTANT used above)
- not supposed to use specific version/versions in the URL
- renamed file from having spaces in the name to `-` instead
