* docs(docs-readme): clarify documentation readme
I was confused what `mitmproxy Python package` meant. At first I did `pipx install mitmproxy`, but that didn't work. Then I realized I needed it as a library/module, not cli.
Changed `build.sh` to `build.py` since it was deleted on commit a7d1f32c89
* Update README.md

Our dev.sh/dev.ps1 scripts feel like an unnecessary layer of abstraction.
The revised docs make the install process transparent to experienced users,
and can also be easily reused for other projects (hi, pdoc!).
