chore(release): migrate to new app version scheme

Align all our application versions that range between 0.x.x and 36.x.x
with different semantics to a single version scheme with distinct
semantics for what constitutes a breaking change.

We have chosen to bump to v100.0.0 to signify the depature from the old
version scheme to the new.

BREAKING CHANGE: App version becomes decoupled from DHIS2 versions, see
the d2.config.js or App Hub for DHIS2 version compatibility.
