Add to the workflow_inputs section of RTD

Pull Request Description

This PR updates the RTD workflow_inputs documentation. The section now specifically provides resources for:

• ACS data for num_buildings_represented
• Utility bill calculation methodology and data sources
• Emissions scenarios

This PR removes details about modifying and writing TSVs as this is done automatically in the resstock-estimation repository.

Checklist

Not all may apply:

- [ ] Tests (and test files) have been updated

• [x] Documentation has been updated - [ ] If related to resstock-estimation, checklist includes data dictionary, source report, options saturation, options_lookup.
• [x] Changelog has been updated - [ ] openstudio tasks.rb update_measures has been run - [ ] No unexpected regression test changes on CI (checked comparison artifacts)

@lixiliu : Thinking about this a little. I have a few thoughts:

• This information is available with our spatial lookup tables and then scaled to the n_buildings_represented value in the project yaml or the ACS vintages.
• If the above resource is not good enough for your uses, I would like for this file to get automatically generated in CI and committed in the "latest commit".
• Also why State level, what about for every "County and PUMA", this way County, PUMA, and State Counts can easily be aggregated.

Let me know what path you prefer.

Summary of our discussion offline: The table is meant as a lookup for n_buildings_represented, not duplicating our spatial tables or tsvs. A "resources" section will be added to README to highlight this file as well as other useful things we've been adding to ResStock to enhance understanding or workflow.
