Fix: Properly format switch expressions

[johnhany97]

Before this PR

Fixes #1025 where before this change, we'd format switch expressions used in an assignment to yield the following:

    public void test2(int y) {
        int x;
        x = switch (y) {
            case 1 -> 1;
            case 2 -> throw new IllegalArgumentException();
            default -> throw new IllegalStateException();};
    }

After this PR

==COMMIT_MSG==
Properly format switch expressions
==COMMIT_MSG==
and now we generate this:

    public void test2(int y) {
        int x;
        x = switch (y) {
            case 1 -> 1;
            case 2 -> throw new IllegalArgumentException();
            default -> throw new IllegalStateException();
        };
    }

Possible downsides?

Drive-by improvement: Didn't see it as necessary to sign the commits made by the test

[johnhany97]

Would like to fix this in the future FWIW to instead be:

        int x = switch (y) {
            case 1 -> 1;
            case 2 -> throw new IllegalArgumentException();
            default -> throw new IllegalStateException();
        };

But that requires more complicated changes to happen to the visitAssignment method which should be left to a separate PR
