Fix redundant AST visitation of elif clause test expressions
Summary
This PR addresses a bug in the AST traversal logic where the test expressions of elif clauses were being visited multiple times.
Removed the initial redundant visitation call to elif test expressions that originally occurred at
ruff/crates/ruff_python_ast/src/visitor/transformer.rs
Line 237 in 0fb94c0
which duplicated the standard processing already implemented at
ruff/crates/ruff_python_ast/src/visitor/transformer.rs
