Sentry tagging improvements

[pedroslopez]

When going through some Sentry issues I found myself wanting a bit more from the tags:

• We should send the docker image as a separate tag, since the release tag is hiding the "package name" and only showing the version, making it a little more work to know what connector this is affecting.
• workspace_id should also be a separate tag - currently it comes through as the user, which is workable but not quite clear
• When working with the issue I often wanted to go into the affected workspace/connection. I can build that link myself by using the workspace id and connection id that are already included in the tags, but we can probably include a direct link instead.

Other notes:

• deployment_mode is currently coming though as OSS. I would expect this to be cloud instead - are we not setting the env variable?
