Issue
Description of Changes
Adds
.github/dependabot.ymlwithtarget-branchentries so Dependabot version updates cover the active release branches1.0,1.1, and1.2in addition tomain.Dependabot only evaluates the
dependabot.ymlon the repository's default branch, so per-branch coverage must be declared there viatarget-branchentries; a config on the release branches themselves would be ignored. This gap showed up with the recent brace-expansion security fix: Dependabot PR #292 bumpedbuild-tools/oss-attribution/oss-attribution-generator/package.jsononmainonly, and the same vulnerable dependency had to be manually bumped on1.0,1.1, and1.2.The new entries mirror the existing npm update configuration (directory
/build-tools/oss-attribution/oss-attribution-generator, weekly schedule), once per release branch. That directory (withpackage.jsonandpackage-lock.json) was verified to exist and be identical onorigin/1.0,origin/1.1, andorigin/1.2; it is the only npm manifest outsidethird-party-srcon those branches, so no other ecosystems or directories were added.Testing

Additional Notes
Dependabot security updates (as opposed to scheduled version updates) always target only the default branch; the
target-branchentries ensure the release branches at least receive scheduled version-update PRs for this directory.Backporting
Not required. Dependabot reads this configuration from the default branch only, so this change on
mainis sufficient to cover1.0,1.1, and1.2.By submitting this pull request, I confirm that you can use, modify, copy, and redistribute this contribution, under the terms of your choice.
