Expand ListFirstAndLast covered cases to include getList().get(0)

[timtebeek]

What's your motivation?

Fixes #423

• ListFirstAndLast skips methodCall().get(0) #423

Anything in particular you'd like reviewers to focus on?

There's still a strong overfit here in:

1. only looking at identifiers (mostly)
2. only supporting getFirst() for method invocations

Have you considered any alternatives or workarounds?

Likely iterate to reduce the overfit.

Any additional context

Would be nice to run these tests in CI, finally

• Run on Java toolchain 21 #337

@timo-abele Would appreciate a review on this, also to see if there's more cases you can think of.

I ran the recipe on my code base, now only lombok generated getters (which we heavily use) are ignored.

Thanks for trying it out! Indeed Lombok support remains in issue, but at least good that we can cover more cases already now.
