fix(deploys) Fix 500 when deploying releases with long names (#12052)

When deploying a release with a long version number we would respond
with a 500 as the `sentry_activity.ident` column would overflow. In
other places where we create activity for releases we truncate the
ident value with this same function.

Fixes APP-1119
