chore(deps): let renovate offer major updates and match the fluentd gem pins

Major updates were disabled for every dependency, which is why thirteen GitHub
actions sit one to four majors behind and one login-action stayed on v2.

The fluentd base image installed fluentd 1.19.2 and oj 3.16.11 while both
Gemfile.lock files resolve 1.19.3 and 3.17.3. The lockfiles move with bundler
updates; these lines never did.
