Description

To allow writing a comment on a PR if the regression tests fail, this PR extracts the artefact from the regression test workflow in the benchmarks repo and then extracts the relevant lines to then post in a PR comment.

Depends on https://github.com/glass-dev/glass-benchmarks/pull/23/files

Closes: #783
