chore: update @sentry/cli to latest major version

update @sentry/cli to latest major version

why

because new users to @sentry/cli will be pulling that major version and if they also use the plugin they'll now have two versions installed - it is probably not an issue but it is damn confusing to have two major versions in the yarn.lock file

Thanks 🙇

nw

however, why did you accept the pull request with a broken build (not like I see it breaking but...)? Seems Sentry 2.x is now only happy with Node 12 and above - IIRC this means we also need to change the matrix in the actions from

node: [8, 10, 12]

to something like

node: [12, 14, 16]

It would also mean a breaking change so an upgrade to the major version number before any publish to npm/github.
