`Download action repository` called repeatedly for actions that have to be the same

[jsoref]

Describe the bug
If an action is used multiple times and the owner or repository name varies in case, then the action will be downloaded multiple times.

As GitHub asserts that owners and repository names are case-insensitive, this is wasteful.

(Note: paths within repositories may be case-sensitive, that's outside the scope of this report.)

To Reproduce
Steps to reproduce the behavior:

1. Create a workflow that uses an action multiple times where the owner/repository name differ only by case -- https://github.com/check-spelling-sandbox/animated-umbrella/actions/runs/13579366005/workflow
2. Trigger the workflow
3. Look at the Set up job section of the workflow run for Getting action download info and Download action repository...

Expected behavior

• Possibly a warning to the job log (::notice ::action requested by multiple cases <...>)
• The action should only be downloaded once

Runner Version and Platform

Version of your runner? 2.322.0

OS of the machine running the runner? Linux

What's not working?

The runner is needlessly downloading multiple copies of an action that it can know to be identical.

For comparison, here's a workflow run where the same action is used multiple times, each time w/ the same case. Note that it only downloads the action repository once:
