incorrect format specifier in ophyd.signal._get_with_timeout()

[prjemian]

Just got bitten by a ValueError: Precision not allowed in integer format specifier coming from this code:

ophyd/ophyd/signal.py

Lines 1057 to 1060 in 6a6ebea

	if info is None:
	raise ReadTimeoutError(
	f"Failed to read {pv.pvname} "
	f"within {timeout:.2} sec")

Is it missing a float specifier? I believe so. Easy fix for two places.
