Upgrade contracts package via CI

[clemsos]

It will be useful to recompile / upgrade the contracts package each time there is any change in contracts, so we make sure that it is up to date - also that we don't break Unlock js and others dependencies.

Oh yes! automate all the things! (after release of the new contracts!)

we could also rebuild the contract docs when a new version of the package is published https://github.com/unlock-protocol/unlock/pull/8807

duplicate of #6091

hey @searchableguy will the package will be released on npm automatically via ci if we bump the version?

[searchableguy]

@clemsos yes and without version bump too if the content has changed, since we bump through yarn version:apply.

so I think we can safely close this
