feat(sentry-cli): Set SENTRY_PIPELINE environment variable (#365)

* feat(sentry-cli): Set SENTRY_PIPELINE environment variable

Set SENTRY_PIPELINE environment variable for all sentry-cli invocations
to identify the plugin and version being used. The value is set to
"sentry-fastlane-plugin/<version>" where version is dynamically read
from the Fastlane::Sentry::VERSION constant.

This allows Sentry to track which integration is being used to upload
data and helps with debugging and analytics.
