Update docs for consistency

[gautamarora]

What: This PR makes minor updates to the documentation for consistent conventions following the new opensource-check project.

p.s. the opensource-check project is very new, so if you have feedback for that, I am happy to update the tool

Why: The opensource-check makes it easy for maintainers to quickly review the conventions their project is following, and to remain consistent. It makes it easy for new users as they discover the repository of a new project. e.g. the downshift project requires no changes as its already consistent, but glamorous has slight deviations.

How: These changes were made by running the opensource-check tool against the glamorous project and fixing the 2 reported issues.

If you would like to try out these changes locally:

1. Clone the glamorous repo
2. Run the check: npx @condenast/opensource-check --path ./glamorous

Checklist:

• [x] Documentation
• [x] Tests
• [x] Ready to be merged
• [ ] Added myself to contributors table
