chore(deps): bump astral-sh/setup-uv from 5.4.1 to 7.3.1

## What

Updated the astral-sh/setup-uv GitHub Action from v5.4.1
(0c5e2b8115b80b4c7c5ddf6ffdd634974642d182) to v7.3.1
(5a095e7a2014a4212f075830d4f7277575a9d098) across all workflow files.

## Why

Aligns with the same dependency bump applied in the contributors repo
(PR #420) to keep all github-community-projects repos on a consistent
setup-uv version.

## Notes

- This is a major version bump (v5 → v7); review the setup-uv release notes for any breaking changes in action inputs or behavior
- The v7.3.1 release adds support for running in containers like debian:testing/unstable
