chore: update @actions/*

[louisbennett]

Updating some of the guts of this action to keep up-to-date with now-vulnerable dependencies.

Changes include:

• update @actions/core and @actions/github to current versions
• update jest to support ESM-only libs (e.g.: @actions/core)
• update packaging process from ncc to esbuild to support ESM-only libs
• update from node20 to node24 as node20 is deprecated

The esbuild packaging command relies on esbuild defaults for module format. Since this repo is a Node20 GitHub Action and the package is not marked as ESM (no type: module), it would be safer to make the output module format explicit (e.g., CJS) to avoid accidental format changes and runtime breakage if esbuild defaults/settings change.
