fix(workflows): simplify manual trigger for scheduled triage (#57)

This commit updates the scheduled issue triage workflow to simplify
manual runs and align it with the source workflow.

The `issue_number` input for the `workflow_dispatch` trigger has been
removed. The workflow now automatically identifies all untriaged issues,
so a manual issue selection is no longer needed. This allows for
manually triggering a triage run for all relevant issues at once.

Additionally, the step that posts a failure comment was removed to avoid
spamming issues if the scheduled triage fails.
