connectors-ci: The Dagger UI url is not displayed in logs

[alafanechere]

All pipeline using dagger in our CI generate a Dagger Cloud run url that is helpful to debug pipeline execution and check what's cached or not.

This URL is only shared in the dagger logs that we persist at the end of the pipeline run to GCS.
It'd be great to get this url in the HTML report and in the GHA logs because it's helpful to track what's going on during pipeline execution.

We have two options to retrieve this url:

• Hacky: Read the dagger logs at runtime in airbyte-ci and parse it when we find the log line "Dagger Cloud run url"
• Ask the Dagger team if we can retrieve this url in a more elegant way with their SDK

grooming:

• first url relates to the git diff
• we do not have access to the correct url at HTML build time
• Lets direct users to the dagger dashboard with commit prefiltered e.g. https://alpha.dagger.cloud/runs?filter=github.com%2Fpr.head:35ee441ef4ad18ccae1116171ebe13877d63543c

Grooming:

1. We should only show this url when _EXPERIMENTAL_DAGGER_CLOUD_TOKEN
2. We should only show this with --is-ci
3. We should output this at the end in a very visually noticeable way that explicitly says in GHA logs, to debug go here

Definition of done:

• The dagger cloud run url is logged to the GHA logs
• It's also shared in the HTML report
• Nothing to do on local: the TUI + setting the _EXPERIMENTAL_DAGGER_CLOUD_TOKEN will be done in connectors-ci: wrap airbyte-ci in dagger run #28869
