Update dependencies for June 2021 (#663)

* Gemfile[.lock]: Update Rails to 5.2.6

Also update its dependency Nokogiri to 1.11.7

* Gemfile.lock: Update Puma to 5.3.2

* yarn.lock: Update browserslist to 4.16.6

* yarn.lock: Update dns-packet to 1.3.4

* deps: Resolve chokidar to 3.x (3.4.2)

* yarn.lock: Update glob-parent to 5.1.2

* yarn.lock: Update hosted-git-info to 2.8.9

* yarn.lock: Update lodash to 4.17.21

* yarn.lock: Update postcss to 7.0.36

* yarn.lock: Update @rails/webpacker to 5.4.0

* yarn.lock: Update ua-parser-js to 0.7.28

* yarn.lock: Update url-parse to 1.5.1

* yarn.lock: Update ws to 6.2.2

* Gemfile.lock: Update rdoc to 6.3.1

* deps: Update [@rails/]webpacker to 5.4.0

Also ran `rails webpacker:install` in the Docker container.

This ensures the packages in `package[-lock].json` and
`Gemfile[.lock]` are in sync with the `webpacker` Ruby gem.

Had to review (and decline) certain conflicting file updates.

* Gemfile.lock: Update addressable to 2.8.0
