* chore: persist the PR number in the Levitate workflow artifact
This is going to be used later in the reporting workflow, as for
3rd party (fork) PRs Github doesn't correctly populate the `workflow_run` context (the PR number is missing from it).
* chore: use the PR number from the artifact for Levitate reporting
* fix(detect-breaking-changes): use the base.ref for backport compatibility
* chore(check-breaking-changes): update path to previous package dist directory
* ci(breaking-changes): split into separate builds for pr and main
* ci(breaking-changes): add path for npm install steps
* ci(breaking-changes): fix up workflow, update bash script
* fix: add col number to the link to work correctly
If we don't provide the position in a #step:{line}:{column} format
then the Github UI won't take us to the correct step.
* fix: escape the backtick ("`") characters properly
* chore: link to the actual workflow step
* chore: make the "Detect" workflow fail if there were any breaking changes
* chore: stop making the reporting workflow fail on breaking changes
* fix: fix typo (`mesage` -> `message`)
