(bump:minor) Feat: Add mechanism for user-site update and auto creating releases (#56)

* move flowsettings.py and launch.py to root

* update docs

* sync sub package versions

* rename launch.py to app.py and make run scripts work with installation package

* add update scripts

* auto version for root package

* rename authors and update doc dir

* Update auto-bump-and-release.yaml to trigger on push to main branch

* latest as branch instead of tag

* pin deps versions

* cache the changelogs
