chore(github): ask issue authors without the fix checkbox about a PR (#16271)

* chore(github): ask issue authors without the fix checkbox about a PR

Issues filed through `gh issue create --body` or the API skip the issue
form, so they never carry the "I am working on a fix" checkbox. When the
"Contributing a fix" section is missing from the body, the triage
workflow now comments asking the author whether they plan to open a
pull request. The regression form gets the same checkbox, so its
reports are not asked.

* test(github): cover the issue fix-intent classifier

The classifier moves from the triage workflow into
.github/scripts/issue-fix-intent.sh, with a test that CI runs next to the
other workflow script tests. The workflow checks out the default branch
before the step so the script is available.

A "Contributing a fix" heading without its checkbox now counts as
missing. A hand-written body containing only the heading was classified
as unchecked and got neither an assignment nor the question.
