Embed errors in issues
## Goal
We want to be able to embed errors in issues, epics, comments, MRs, by simply copying a link a link from the GOUI.
- highlights one of the true benefits of building all this into GitLab
- simply pasting the link will embed the iframe
- adding backticks will do the natural thing of making it unformatted text
- adding it into link syntax `[]()` will make it a clickable link instead of an embbed.
- display a small iframe pointing to a specific trace/error
## Progress
- TODO - Embed `Explore telemetry data` views
- ✅ DONE - Embed dashboard panels
- Note that this works, however the `Dashboard` page is currently hidden in the GOUI - https://gitlab.com/gitlab-org/opstrace/opstrace-ui/-/issues/176+
- Example: https://observe.gitlab.com/9970/d/5obPHCc4k/example-dashboard?groupId=14485840&from=1671703158676&to=1671724758676&orgId=14485840
