fix: add attributes to get_meter wrapper

[Maxi91f]

Description

On #4015 the attributes parameter was added for meter providers, and all interfaces were updated, but the global wrapper was not updated with the new API.

Since the function doc says that "This function is a convenience wrapper for opentelemetry.metrics.MeterProvider.get_meter." I expect this to have the same parameters.

How Has This Been Tested?

First I started a aws-otel-collector docker container for testing
Then I run this minimal script.

from opentelemetry import metrics
from opentelemetry.exporter.otlp.proto.grpc.metric_exporter import OTLPMetricExporter
from opentelemetry.sdk.metrics import MeterProvider
from opentelemetry.sdk.metrics.export import PeriodicExportingMetricReader

exporter = OTLPMetricExporter(endpoint="localhost:4317", insecure=True)
metric_reader = PeriodicExportingMetricReader(exporter)
metrics.set_meter_provider(MeterProvider(metric_readers=[metric_reader]))
meter = metrics.get_meter("test", attributes={})

Without this PR this fails with

TypeError: get_meter() got an unexpected keyword argument 'attributes'

Now is working as expected.

Hi!

First time contributor here.

I didn't knew if I needed to change the changelog or not. LMK if needed.

Also, I couldn't find a specific test just for this specific interface, or any API in fact, so I didn't wanted to add a new test. But LMK if it's needed.

@Maxi91f welcome! please add a changelog entry and also add a test in opentelemetry-api/tests/metrics/test_meter_provider.py since it doesn't look this helper is tested

Thanks for the response @xrmx ! I'm doing it.
