Resolve "Multi-project pipelines in Web IDE lead to 404"

What does this MR do?

This MR changes the serialized job so that it doesn't contain a link to the non-existent details page and uses the presence of the detail page path to decide whether to show the link to this job in Web IDE (build job) or hide it (bridge job). We are hiding bridge job links because bridge jobs don't have their own detail page (i.e. /:group/:project/-/jobs/:job_id).

The serialized JobEntry is only used in Web IDE (I wasn't able to find any other usages).
