workflow_dispatch on to allow manual run of action

[maneesha]

In addition to having scheduled actions, I would like us to have the ability to manually run an action (so we don't have to wait for the next scheduled run if we fix a bug or make a change in between). According to the instructions on how to manually run a workflow, it says workflow_dispatch must be on. I would like to have someone who knows more about GH Actions than me to review this and be sure it won't cause a conflict with the scheduled runs. Tagging @zkamvar or @froggleston or @elichad

I don't know if the failing checks are because of the meta nature of this PR (running an action on a change in action) or something else. I don't see anything wrong with the workflow. Further reading:

I don't see anything particularly wrong with the workflow either. It looks like the echo github context is getting borked because of some weird character not properly escaped. I would say this is fine to merge.

ugh, it turns out it wasn't benign. Let's delete that show github context. it's not doing anything but hurting us.
