fix: allow to build readme in 01_start

tags: fix, doc

Why?  

- I need to be able to commit right after running the complete "dev/01_dev.R"

How?

- To commit, I need the Readme.md file to be created, after I created the Readme.Rmd file.
- devtools::build_readme() allows to install the package temporarily with its last version to be able to knit the Readme.Rmd in the last good conditions
