[release] Indicate what remote service exactly is not available when things fail

Is your feature request related to a problem? Please describe.

My release failed with the following exception:

Error:  Failed to execute goal org.jreleaser:jreleaser-maven-plugin:1.7.0:full-release (default-cli) on project ttcli: Execution default-cli of goal org.jreleaser:jreleaser-maven-plugin:1.7.0:full-release failed: Unexpected error when creating release: org.jreleaser.sdk.commons.RestAPIException: 503: Service Unavailable -> [Help 1]

(See https://github.com/wimdeblauwe/ttcli/actions/runs/5622632049/job/15235883963 for the full logs)

Unfortunately, I have no idea exactly what remote service is not available (brew, chocately, ... ?). It would be nice if the exception could also print the URL it is trying to reach.

Describe the solution you'd like

It would be nice if the exception could also print the URL it is trying to reach.

Based on the log the problem happened posting the release to Github, not with the packages.

However, adding URLs to the trace log would be OK.
