coverage reports attached to merge commits on pull requests about go-coverage-action

[gwatts]

Hi @shinenelson - Thanks for the detailed report!

I actually intended this action to be used in conjunction with a push event as well on the main branch so that the coverage is tracked for commits on that branch

The problem with relying on notes attached to commits in the PR is that they're essentially lost when/if the branch is rebased or squash-merged as the hash will change.

Fair enough. It would be helpful to add this to the ReadMe so that another user who attempts to run this action only on: pull_request event would not be confused by this " intended behaviour "
