add clarification

[Karim-Mane]

• In the Consideration for Tidyverse vs. Base R section of the Epiverse-TRACE Package Dependency Guidelines chapter, is it possible to add definitions around the meaning of low-level and high-level packages?

• • In the Additional Recommendations section of the Epiverse-TRACE Package Dependency Guidelines chapter, can we make the generation of design vignette mandatory for all package and may be list specific cases when this is not needed?
