action.yaml: fix message-template

[pjonsson]

The message template contains four dashes,
and that apparently makes Github not render
the following books emoji. Use three dashes
instead.

The non-displaying emojis can be seen in #12,
or #16 for something more recent.

This requires #33 to be merged before passing the CI.

Thank you for the fix! 🙇🏻‍♂️

I did some tests here and I wasn't able to reproduce the issue. Please, see #34 (comment) to see how we continue moving forward.

Not being able to reproduce seems concerning. Here's a screenshot of this PR from my screen:

The lower left corner contains the characters "books" between colons, rather than an emoji of books, so this repository is still affected for at least some of us.

I see the same here. I tried editing the description to remove a - and I was not able to make it work 🤷🏼

Also, I don't know why it started to failed now. I was working before. So, GitHub has changed something?

[pjonsson]

Your main repository uses a custom message, so you don't see the issue there. (That is where I found the solution to the problem.)

#12 is from August 2022, so it's been around for a while.

I did this PR 9 days ago so I don't remember when you added the XML comment to keep track of the URL, but it's possible that is what caused things to break.

[pjonsson]

Even if this PR is wrong, could you check/reject-and-make-some-other-fix #33 first so PRs to this repository aren't automatically red?

[humitos]

I merged #37 which uses the real emoji instead of :books:. After opening a new PR #38 I can see the emojis properly rendered there. @egeakman @pjonsson let me know if it works for you.

[pjonsson]

Strange, my first attempt at fixing this was identical to your PR, but didn't work for some reason.

It works now though, thanks!
