metric emission fails with multiple GOEXPERIMENT values

[jstncbllr]

Expected Behavior

Given an env var like GOEXPERIMENT=boringcypto,jsonv2 metrics should work.

Actual Behavior

The library tries to emit a value like this, resulting in an error in cloudwatch logs:

DD_EXTENSION | ERROR | Failed to parse metric  ....  dd_lambda_layer:datadog-go1.25.1 X:boringcrypto,jsonv2: parse failure: Invalid tag format

Steps to Reproduce the Problem

Try to use more than one go experiment.

FWIW I made a disgusting workaround here.
