Support publishing packages from other branches

[bebbs]

I maintain a package where the default branch name is main instead of master, I think it may also be the jackfan.us.kg-wide default for new repositories now (?)

Would love to use elm-publish-action to automate publishing new versions, but to do that I think this action would have to support publishing packages from main as well as master? It looks like it checks for refs/heads/master only here:

elm-publish-action/src/main.ts

Line 36 in 67ef64e

if (githubRef !== 'refs/heads/master') {

Would a patch to allow publishing from main / master, or a more generic solution to make it configurable be welcomed?

Hello @bebbs! Ah yes, great point. It would be great to use the repo's default branch. There's already a feature to help with this: https://github.blog/changelog/2020-07-22-github-actions-better-support-for-alternative-default-branch-names/. So we should be able to just use $default-branch now instead of hardcoding the branch to master.

Happy to discuss more if you have any other thoughts.
