Fix goreleaser parallel builds (use CLI flag, not config field)

[dustman9000]

Follow-up to #955. The parallelism field doesn't exist in goreleaser's build config schema -- it needs to be passed as a CLI flag instead. This caused the release to fail immediately with a YAML unmarshal error.

Changes:

• Reverts the invalid parallelism: 2 from .goreleaser.yml
• Passes --parallelism 2 via the goreleaser action args in both release.yaml and release-on-version-bump.yaml

Summary by CodeRabbit

• Chores
  • Limited release build parallelism to improve build stability.
  • Applied the same release configuration consistently across automated release workflows.

Walkthrough

The release workflows now pass --parallelism 2 to GoReleaser. The shared GoReleaser configuration no longer defines the build parallelism limit.

Changes

Release parallelism

Layer / File(s)	Summary
Workflow-controlled GoReleaser parallelism .goreleaser.yml, .github/workflows/release-on-version-bump.yaml, .github/workflows/release.yaml	The shared configuration removes parallelism: 2. Both release workflows pass --parallelism 2 to GoReleaser while retaining clean releases.
