Disable linter for dependabot PRs

Because this repository uses vendored dependencies, and grouping for
dependabot updates, the PRs created by dependabot are huge. This causes
issues for the linter:
    golangci/golangci-lint-action#996
The chances of dependabot creating new linting issues are minimal.
