👷 manage checkTelemetryError connexion pool

[thomas-lebeau]

Motivation

The deploy-minor-dc job fails consistently, with a ECONNRESET error to the call of the logs API (checkTelemetryErrors())

Interestingly, checkTelemetryErrors() is called successfully before the deploy and source-maps upload scripts, but not after. This leads us to think this might be due to a connexion pool exhaustion issue.

Unfortunately, I'm not able to reproduce the failing outside of the release.

Changes

Integrate 'undici' HTTP agent in checkTelemetryErrors(), enforcing a new connexion pool is used at each call.
