Release 7.20 is not compatible with CircuitPython 5.3.x

[roamingthings]

While trying to advertise something using start_advertising() I constantly ran into an error:

...
File "adafruit_ble/init.py", line 191, in start_advertising
TypeError: extra keyword arguments given

After comparing the documentation of CircuitPython 5.3.x and the current version (6.x.x) regarding the underlying call to start_advertisingof Adapter 5.3.x / 6.x.x
I realized that Release 7.2.0 of this library introduced an incompatibility with CircuitPython 5.3.x:

Adafruit_CircuitPython_BLE/adafruit_ble/__init__.py

Lines 186 to 191 in 9af3aff

	self._adapter.start_advertising(
	advertisement_bytes,
	scan_response=scan_response_bytes,
	connectable=advertisement.connectable,
	interval=interval,
	timeout=0 if timeout is None else timeout,

Which has too many parameters for CircuitPython 5.3.x

Unfortunately I'm new to (Circuit)Python so I don't know if it would be possible to have a library that is compatible with both versions of CircuitPython.
I also unterstand that (for now) I have to use Version 7.1.0 to be compatible with CircuitPython 5.3.1

Oops, sorry! I will add code to check the version or fall back to no timeout. I will reference you on a PR soon.
