Dependabot will periodically check the versions of all actions used in the repository's workflows. If any are found to be outdated, it will submit a pull request to update them.
NOTE: Dependabot's PRs will occasionally propose to pin to the patch version of the action (e.g., updating uses: foo/bar@v1 to uses: foo/bar@v2.3.4). When the action author has provided a major version ref, use that instead (e.g., uses: foo/bar@v2). Once the major version has been updated in the workflow, Dependabot should not submit an update PR again until the next major version bump.
So even when the PRs from Dependabot are not exactly correct, they still have value in bringing the maintainer's attention to the fact that the action version in use is outdated. Dependabot will automatically close its PR once the workflow has been updated.
