feat(cli): Set SENTRY_PIPELINE environment variable for all sentry-cli invocations (#1036)

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

This sets SENTRY_PIPELINE to 'sentry-gradle-plugin/<version>' for all sentry-cli
invocations, enabling better pipeline tracking and analytics on the server side.

The environment variable is now set in:
- SentryCliExecTask (base class for all CLI execution tasks)
- SentryCliInfoValueSource (for CLI info gathering)
- SentryCliVersionValueSource (for CLI version detection)

* refactor(cli): Centralize SENTRY_PIPELINE environment variable setup

Extracted the SENTRY_PIPELINE environment variable setup into a reusable
extension function `ExecSpec.setSentryPipelineEnv()` in SentryCliExec.kt.
This eliminates code duplication and provides a single source of truth for
setting the pipeline environment variable across all sentry-cli invocations.
