Initial clean-up of StorageSystemsSimulations documentation

[kennedy-mindermann]

The existing StorageSystemsSimulations documentation needs to be cleaned up prior to reorganizing with the new Diataxis format. This includes:

• [x] Upgrading to Documenter > 1.0
• [x] resolving errors to enforce strict compilation by removing warnonly=[:missing_docs], after Kate adds "How to resolve missing docstrings" to docs best practices
• [ ] Adding .md formatting to the formatter script
• [ ] Proof-reading for formatting and misformatted code references
• [ ] Adding hyperlinks everywhere
• [ ] Reorganize top level headings for Diataxis
• [ ] Review existing quick start guide and welcome page, and organize by Diataxis (See PowerSystems for example)
• [ ] Map current tutorials to either Tutorials or How-tos
• [ ] Replicate Reference format from PowerSystems.jl
• [ ] Add Formulation Library under Reference
• [ ] All docs references must be in the API. All docs references in Formulation Library should be referenced as non-canonical: https://documenter.juliadocs.org/stable/man/syntax/#noncanonical-block
• [ ] To figure out: Should Attributes list be an arguments list? Compare to what's going on in PowerSimulations
