Remove CGO build flag

[friegger]

CGO is not required anymore.

This fixes also a problem with the recent release drafter bump.

Summary by CodeRabbit

• Chores
  • Simplified release automation by adjusting workflow triggers and conditional steps for PRs, pushes, and manual dispatches.
  • Standardized build and lint invocations by removing explicit environment overrides, relying on tool defaults for more consistent builds.

📝 Walkthrough

Walkthrough

Replaced workflow trigger pull_request_target → pull_request, added a gate so one drafter step runs only on push or workflow_dispatch, and removed explicit CGO environment overrides from Go build/lint invocations in Dockerfile and Makefile.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow .github/workflows/release-drafter.yml	Changed on trigger from pull_request_target to pull_request. Updated autolabeler condition to github.event_name == 'pull_request'. Added condition so the second drafter step runs only when github.event_name is push or workflow_dispatch.
Build & Lint Commands Dockerfile, Makefile	Removed explicit CGO_ENABLED environment settings: dropped CGO_ENABLED=0 from go build/go install in Dockerfile, and removed CGO_ENABLED=1 prefixes from Makefile targets (lint, lint-fix, build).
