Subject: [PATCH] Bring back the inclusion of telemetry_poller in releases
 (#2324)

The `runtime: false` option in mix.exs was the wrong one to use: it
excluded the dependency from release packaging, resulting in the release
startup failure when `ELECTRIC_USAGE_REPORTING=true`.

The correct way to make telemetry_poller's default reporting disabled is
to configure it as such.

Fixes https://github.com/electric-sql/electric/issues/2323.
