feat: add workflow to create and push pkg Go module version tags

[Copilot]

The pkg/ subdirectory is a separate Go module (github.com/supabase/cli/pkg) requiring its own semver-prefixed tags (e.g. pkg/v1.2.2) for Go module versioning. No automation existed to create and push these tags.

Changes

• .github/workflows/tag-pkg.yml: New workflow_dispatch workflow that:
  • Accepts a version input (e.g. v1.2.2)
  • Validates it matches semver format (v{major}.{minor}.{patch})
  • Guards against re-tagging by checking if the tag already exists
  • Checks out develop at HEAD and creates + pushes pkg/<version> tag

Usage

Trigger manually from the Actions UI with the desired version to tag the current HEAD of develop:

version: v1.2.2  →  creates and pushes tag pkg/v1.2.2

Original prompt

Create a tag for pkg/v1.2.2 and push to develop branch

Pull request overview

Adds a manual GitHub Actions workflow to create Go module semver tags for the pkg/ submodule (github.com/supabase/cli/pkg) using the pkg/vX.Y.Z tag prefix, enabling proper Go module versioning automation.

Changes:

• Introduces a workflow_dispatch workflow to tag develop HEAD as pkg/<version>.
• Adds basic input validation for v{major}.{minor}.{patch} and a guard to prevent re-tagging.
