Is your feature request related to a problem? Please describe.

Dependabot continues to fail to raise PRs for pub deps.

Describe the solution you'd like

args to be bumped to 2.6.0
at_commons to 5.0.1

Should we take this opportunity to bump dev dependencies like lints (still at ^1.0.1 in at_persistence_root_server)? Also increment patch version for each pubspec? 👀 @gkc
