We can't target 2.9.0.beta7 because it pins the plugin version on installed on `tests-passed` site because the Discourse version in `tests-passed` is 2.9.0.beta7.

Discourse `main` branch is currently on beta3 so we can't lock the plugin version against that because otherwise the plugin would be locked at e7c19ac107 until core's bumped to beta4.
The reverted commit pinned the plugin version on stable because the changes in that commit aren't compatible with stable. However, the version that we pinned the plugin to has a bug on stable and 50e62d84e8 fixes that bug. So we need to temporarily revert 5e24556b24 to unpin the plugin and I'll create another PR to undo this revert and re-pin the plugin version to this commit for sites on stable.
