Bump bleak-esphome to 2.0.0

[bdraco]

Proposed change

There is a fix to move the caching to be per ESP device since different ESP chips/major versions can generate different services for the same device. Previously we had a global cache that was shared between all ESPHome Bluetooth proxies which could result in writing to the wrong handle if all the ESPs were not the same

changelog: Bluetooth-Devices/bleak-esphome@v1.1.0...v2.0.0
