ci: sync resource labels, auto-label issues, and consolidate bug report templates (#2628)

## Summary

### Sync GitHub labels from provider schema
Adds a workflow (`sync-labels.yml`) that creates GitHub labels with
`resource/` and `data-source/` prefixes for every resource and data
source in the provider schema. Triggers on changes to
`provider_schema.json` on `main` and via manual `workflow_dispatch`.
Stale labels are intentionally kept to preserve historical context on
older issues/PRs.

### Auto-label issues from bug report dropdown
Adds a workflow (`issue-label-resources.yml`) that parses the "Affected
Resource(s)" dropdown from the bug report template and applies the
matching `resource/` and `data-source/` labels to the issue. When an
issue is edited, old resource labels are removed first so the labels
stay in sync with the selection.

### Consolidate bug report templates
Removes the plain-text bug report template and promotes the enhanced
version (with the resource dropdown) as the sole bug report template.
Updates `generate_issue_template.go` and `update-schema.yml` to
reference the new filename.

### Disable blank issues
Disables blank issue creation for non-maintainers and adds a contact
link pointing to GitHub Discussions for questions.

### Auto-approve and auto-merge schema update PRs
The `update-schema.yml` workflow now approves and enables auto-merge
(squash) on the PRs it creates. The GitHub App creates the PR and
`GITHUB_TOKEN` (github-actions[bot]) approves it, satisfying the
1-review requirement. The PR merges automatically once required status
checks pass.

## Test plan

- [ ] Trigger `sync-labels.yml` manually via `gh workflow run
sync-labels.yml` after merge
- [ ] Verify labels are created with correct prefixes, colors, and
descriptions
- [ ] Create a test issue using the bug report template, select
resources, and verify labels are applied
- [ ] Edit the test issue to change selected resources and verify labels
are updated
- [ ] Verify blank issues are disabled for non-maintainers and the
Discussions link appears
- [ ] Verify schema update PRs are auto-approved and auto-merged after
checks pass
