Update to Checker Framework 3.22.2

[lazaroclapp]

Needed for our changes in #608, which requires visibility into some previously
package or private level internals of Checker Framework's CFG:

• Make the Label class public typetools/checker-framework#5152
• Expose some cfg/builder APIs to allow inserting jumps and throws. typetools/checker-framework#5156

Not sure if we want / need to perf test this on its own. The data flow library is pretty stable
these days

We probably want perf testing on #608 itself once that is ready - if you haven't checked already - but your call on the dependency upgrade itself. Would be nice if perf testing was automated for every PR, but I imagine that's far from trivial :)

I did an overhead measurement for #608 (which currently includes this change) and everything was fine; so I think this should be ok on its own.
