pyglove/backend.py: remove invalid characters after function decorator

[ConnorBaker]

Removes (what I think is) a bad edit introduced in 5aad0c0#diff-f913e6960ace197c5499de1d7a0da89de6a4e5e567b18e11b963e3b38c094c2aR381:

  @functools.lru_cache(maxsize=None)d_property
  def _tuner_id(self) -> str:
    """Returns the tuner id of current ."""
    return self._tuner.get_tuner_id(self._algorithm)

d_property isn't defined anywhere and causes the interpreter to throw a SyntaxError

CC @daiyip -- am I missing something?

Thank you Connor!

This was a bug in our release to github process, bundled with the fact that our Github tests for Pyglove were disabled and we didn't notice that.

This also caused #1031

Working on a PR to fix both issues properly, please stay tuned.
Thank you for reporting!

Best,
Sagi
