Commit releases to master

[talon]

Is your feature request related to a problem? Please describe.
Currently the version key in every package.json on the master branch is wrong, though it is published correctly in the registry

also yarn workspaces requires versions so it'll be nice to have them up-to-date

also if you don't build on master before commiting the README's aren't there, but still they are published correctly

Describe the solution you'd like
Wiring up https://github.com/semantic-release/git should commit the releases to master and resolve this

Describe alternatives you've considered
I'm not gonna manually update them if that's what you're asking 🤣

Additional context
I've dealt with enough monorepo mayhem and will be avoiding trying this for now 🤕 but eventually it would be nice
