Add Galaxy overwrite check and use gh for release

[lowlydba]

Description

• Added a new overwrite_existing boolean input to the release workflow, allowing users to overwrite an existing Galaxy release if needed. The workflow now checks if the specified version already exists and aborts unless overwriting is explicitly enabled.

• Added a validation step to ensure the input version matches the version specified in galaxy.yml, preventing accidental mismatches during release.

• Improved artifact handling by uploading the built collection as a workflow artifact after publishing to Galaxy.

• Replaced the use of the softprops/action-gh-release action with a direct gh release create command for creating GitHub releases, simplifying the release step and reducing dependencies.

• Updated the local_pwsh.py test connection plugin to dynamically locate the pwsh executable using shutil.which, with platform-specific fallbacks, making the test setup more robust across different environments.

  • This fixes the broken dlevel tests - apparently the pwsh install directory is more of a moving target these days than when it first came out, so using dynamic resolution is needed as of 2.21+

Pull request overview

This PR updates the project’s release automation and integration test tooling by enhancing the GitHub Actions release workflow (Galaxy prechecks, artifact upload, gh-based GitHub release creation) and making the local_pwsh connection plugin more robust by dynamically locating the pwsh executable.

Changes:

• Add release workflow preflight checks (Galaxy version existence + galaxy.yml version match) and an overwrite_existing input gate.
• Upload the built collection tarball as a workflow artifact after publishing.
• Replace softprops/action-gh-release with gh release create for GitHub release creation.
• Update the local_pwsh test connection plugin to resolve pwsh via shutil.which() with platform fallbacks.

The Galaxy existence check treats any curl failure (network/DNS/timeout/5xx) the same as “version does not exist” and proceeds, which can lead to attempting a publish/release under uncertain Galaxy availability. Consider capturing the HTTP status explicitly and only treating 404 as “does not exist”; for other non-success statuses or curl transport errors, fail the job so the release isn’t created based on a false negative.
