Fix readline history truncation when length is reduced

  The `readline.set_history_length()` function did not previously
  truncate the in-memory history when the new length was set to
  a value smaller than the current number of history items. This
  could lead to unexpected behavior where `get_history_length()`
  would still report the old length and writing the history to a
  file would write more entries than the new limit.

  This patch modifies `set_history_length()` to explicitly
  remove the oldest history entries using `remove_history()`
  when the length is decreased, ensuring the in-memory history
  is correctly truncated to the new limit. This brings the
  function's behavior in line with expectations and fixes
  failures in `test_write_read_limited_history`.
