[PMPDD-72]: Fix warning on attaching an anonymous function to telemetry

While I was upgrading dependencies on scrivania, I noticed the following warning

[info] The function passed as a handler with ID "repo-init-handler" is a local function.
This means that it is either an anonymous function or a capture of a function without a module specified. That may cause a performance penalty when calling that handler. For more details see the note in `telemetry:attach/4` documentation.

https://hexdocs.pm/telemetry/telemetry.html#attach/4

not a big problem, but I thought it would be nice to remove it from future versions.
