Final updates

[mkavulich]

A (hopefully) final set of updates prior to the v6 release:

• Add section on new variable tracking tool
• Update links for v6 release (SCM UG link is still broken, but should be live soon)
• Remove mentions of MRW/Global for this release
• Some formatting and spelling fixes
• Update Acronyms and Glossary, clean up links to Glossary
• Remove mentions of optional arguments

You can view the latest version of this branch's proposed changes in ReadTheDocs here: https://mike-k-tech-doc.readthedocs.io/en/latest/index.html

I am still in the process of cleaning up the Glossary references, but I shouldn't make any more substantial changes to this PR.

Thank you another round of informative updates.

• All the links to the CCPP-SCM Users Guide need to be changed to https://dtcenter.org/sites/default/files/paragraph/scm-ccpp-guide-v6-0-0.pdf, with dashes instead of dots in the file name because neither Dustin nor I have managed to make Drupal display the file name with dots.
• VLAB could be removed from list of acronyms and glossary (it no longer appears in the document).
• In https://mike-k-tech-doc.readthedocs.io/en/latest/AutoGenPhysCaps.html, pls start List of variables provided by host model and required by physics on a new line and hide asterisk

@ligiabernardet Thank you for your thorough review and all the comments and corrections! I believe I have addressed all of your comments, let me know if you have anything else.

I believe the ReadTheDocs has been updated. In that case, there is a broken link from https://mike-k-tech-doc.readthedocs.io/en/latest/ConfigBuildOptions.html?highlight=ufs%20wm#ccpp-configuration-and-build-options to the UFS WM UG. This is related to EPIC changing the branching/tagging/releasing naming convention.

Same broken link from https://mike-k-tech-doc.readthedocs.io/en/latest/ConfigBuildOptions.html?highlight=guide#ccpp-configuration-and-build-options to https://ufs-weather-model.readthedocs.io/en/ufs-v3.0.0/BuildingAndRunning.html#building-the-weather-model

[ligiabernardet]

Almost there. Just a couple of broken links.

Refreshed on my end and links work now.
