[CodeQuality] Preserve parentheses around right-side assign in LogicalToBooleanRector

Fixes rectorphp/rector#9799

When an assignment sits on the right/nested side of a converted boolean
operator, the printer reused the Assign node verbatim and dropped the
parentheses the pretty-printer would add in context:

    true and ($x = 42) and false;
    // became: true && $x = 42 && false;  ->  $x = (42 && false) = false

The right-side reprint was guarded by !haveParens, but source parens live
in the parent node token range (not the Assign node), so the guard skipped
the reprint and the parens were lost anyway. Reprint unconditionally; the
pretty-printer only adds parens when semantically needed.
