hmm I don't agree too much with this, it makes things easier to have the version of the tool written down somewhere. Moreover, right now the version of the tool and the action are the same by accident, I will think of moving the action elsewhere (in @haskell-actions for instance), and then it will be a totally different number.

You are definitely right there in principle. My motivation was the following: I like and use get-tested a lot, but one common source of errors was that I used a newer GHC version than my pinned get-tested version supported. If the version of the action is bumped every time the version of the tool is bumped, then dependabot can automatically bump that version in my local usage of the action. If you want to decouple the two, you would have double the maintenance effort by bumping two versions.

Ah yes that was a problem of fixed known GHC versions, but I've removed this behaviour: 3e5545e

(or perhaps were you thinking of something else?)

I just tested and it seems that is exactly the thing :D ok, in that case my workflow doesn't depend so crucially on the get-tested version anymore and all is well. Thanks!
