[BUG] Using source_hash when renaming a file shows warning of unsupported protocol

Description

file.managed documentation states that source_hash:

When using a source hash file the source_hash argument needs to be a url, the standard download urls are supported, ftp, http, salt etc

Local file could be mentioned before the "etc".

It was fixed in code in:

• https://github.com/saltstack/salt/pull/44794

Having the warning message is worrying because it is read as it no checksum was made, but it was made, as I tested with the wrong checksum and it failed.

Setup
(Please provide relevant configs and/or SLS files (be sure to remove sensitive info. There is no general set-up of Salt.)

Please be as specific as possible and give set-up details.

• VM (Virtualbox, KVM, etc. please specify) - Xen - QubesOS
• classic packaging - packaged by Qubes developers

Steps to Reproduce the behavior
(Include debug logs if possible and relevant)

I ran the state locally.

id:
  file.managed:
    - name: /tmp/a
    - source: /tmp/b
    - source_hash: sha256=theshasum

[WARNING ] source_hash is only used with 'http', 'https' or 'ftp'

File is correctly copied if the hash is correct and not copied if it is incorrect.

In case it is incorrect:

     Comment: Specified sha256 checksum for /var/lib/qubes/vm-kernels/vmlinuz (18a1ee52574b9a4fc5eda265922bcbcface90f7c43ed7a68dc8e201a2ac0a7dc) does not match actual checksum (78a1ee52574b9a4fc5eda265922bcbcface90f7c43ed7a68dc8e201a2ac0a7dc)

Expected behavior

No warning message and the documentation stating that local files are also supported.

Additional context

Start with the file.managed state and its source_hash handling, using the provided local-source SLS example to reproduce the warning. Check the file.managed documentation alongside the warning path and the behavior described in pull request 44794. Done means local files are checksum-validated without the unsupported-protocol warning and the documentation mentions local files.
