Tell more clearly in logs which deployment got skipped

Currently, only this generic message is shown:
“Skipping a deployment with the releases provider because a custom condition was not met”

It does tell you which provider was skipped, but the naming is misleading. If you use GitHub releases it should tell you so and not use the unclear term “releases provider”. I should tell you “GitHub releases provider” for example.

At best one could give the deployment stages names (or use those from the build jobs), and those names would be printed there. You can not really tell which one go skipped and which one is running, especially if you use the same provider multiple times:
“Skipping the deployment with the GitHub releases provider for XYZ because a custom condition was not met” or similar.
