SCD30 ignoring update_interval

The problem

It seems that https://github.com/esphome/esphome/pull/2308 broke update_interval for the SCD30. The interval is written to the SCD30 sensor, but it doesn't have an effect on how often the sensor is read. It seems that this change initially worked, or it depends on the firmware of SCD30 (my SCD30 Firmware v3.66) - I don't know how to verify this. It does not work for my SCD30s, and I've multiple of them.

The data sheet of the sensor doesn't say that you can't read the sensor faster than the configured update interval. I think the update interval of the sensor is more like "this is when I have valid data ready".

So as the component is no longer a PollingComponent, updating happens as quickly as possible, which is 2s (as this is the minimum interval of the sensor).

I'm very new to ESPHome, but my best guess is, that this should actually be a PollingComponent, as we need to schedule updates according to update_interval.

Overall, this doesn't seem to be a big issue, but it feels wrong:

setting an update_interval for the sensor, but update_interval has another meaning in ESPHome as I understand.
getting updates every 2s even if you set an update_interval - not expected behavior.

I'm happy to help with testing.
