Bump and simplify a dep and a plugin.

The main motivation to this CL is to pick up [a fix to Animal Sniffer](mojohaus/animal-sniffer#212): The old version of Animal Sniffer ignores suppression annotations when it looks at fields, and that was causing me problems as I tried to use a field of type `FileAttribute`.

While I was at it, I ran the usual command for updating deps (but not plugins), as documented in cl/503506407.

And then, I inlined a couple properties into the `dependencyManagement` entries that used them. We'd introduced the properties because we used to use multiple artifacts that were released together. However, we don't use multiple artifacts with those properties anymore:
- We stopped using the Animal Sniffer _annotations_ way back in cl/273964192, leaving only the Animal Sniffer plugin.
- We stopped using the Checker Framework's `compat-qual` annotations back in cl/399471446 - cl/399480336, leaving only the main `qual` annotations.
  - But we had temporarily introduced a usage of the `sources` artifact for `qual` in cl/364918297. We removed the usage of it in cl/399190627 but left behind the `dependencyManagement` entry. So this CL removes that, too.

(It's possible that we'd want to move away from using properties for versions in general: While Guava doesn't use Dependabot for `pom.xml` updates (only for GitHub Actions updates, which are easily for our tools to import), we can still update all deps by running a command. So we're not stuck hand-editing multiple locations, and thus all the property provides a layer of indirection. However, until we have a way to automatically update _plugins_, there is some sense in using properties for _plugin_ versions. Or at least there's sense in it for any properties that we still need to use in multiple places. But we might not need to use many (any?) in multiple places anymore, since we finally solved the mystery of why our `pluginManagement` section wasn't being respected back in cl/492304151....)
