Please tag a new release of `ament_lint` for `foxy`

[esteve]

Because of the changes in Pydocstyle 6.2.0 (addressed in #431), foxy's latest tagged version of ament_lint makes tests fail.

humble and rolling already have tagged releases that incorporate this change, but unfortunately foxy doesn't and it's causing projects that use https://github.com/ros-tooling/setup-ros to fail their CI jobs, due to the latter updating Pydocstyle to the latest version during the setup-ros phase. Thanks!

So this seems to be taken care of in 0.9.8 (see 0.9.7...0.9.8), closing it out!
