Allow installing SDK with API v1.5

[IonBazan]

Currently open-telemetry/sdk locks open-telemetry/api at 1.4.0 and does not allow upgrades to 1.5.0 due to incorrect version constraint. Fixes #1706

  Problem 1
    - Root composer.json requires open-telemetry/sdk ^1.7 -> satisfiable by open-telemetry/sdk[1.7.0].
    - open-telemetry/sdk 1.7.0 requires open-telemetry/api ~1.4.0 -> found open-telemetry/api[1.4.0] but the package is fixed to 1.5.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
  Problem 2
    - open-telemetry/exporter-otlp is locked to version 1.3.2 and an update of this package was not requested.
    - open-telemetry/exporter-otlp 1.3.2 requires open-telemetry/sdk ^1.0 -> satisfiable by open-telemetry/sdk[1.7.0].
    - open-telemetry/sdk 1.7.0 requires open-telemetry/api ~1.4.0 -> found open-telemetry/api[1.4.0] but the package is fixed to 1.5.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

the only way to update at the moment is to downgrade the API package:

$ composer u open-telemetry/sdk -W
