Update open-telemetry/opentelemetry

An error occurred when performing composer install.
So I upgraded the dependencies.

Error

  Problem 1
    - Root composer.json requires open-telemetry/opentelemetry ~0.0.9, found open-telemetry/opentelemetry[dev-main, 1.0.0beta, 1.0.0beta1, 1.0.0] but it does not match the constraint.

How I fixed

1. I changed "open-telemetry/opentelemetry": "~0.0.9" to "open-telemetry/opentelemetry": "~1.0.0".
2. Re ran composer install.
3. I inputted y for Do you trust "php-http/discovery" to execute code and wish to enable it now? (writes "allow-plugins" to composer.json) [y,n,d,?].
4. I ran ./vendor/bin/phpunit tests, and it was successful.
