Multiply assets injection

[ink-ru]

Description
Assets (js, css) included over "resource" with etag (to prevent caching) config param appear in code tree times

To Reproduce
Steps to reproduce the behavior:

1. Put some links to /config/platform.php with unique names (reproduced with assets in public folder)
2. Open any page (found on login page) and open development console (F12 for chrome)
3. On Elements tab press Ctrl+F and type name of your asset to find them in code

Expected behavior
Assets have to be included only once

Desktop (please complete the following information):

• OS: Cross
• Browser: Cross

Server (please complete the following information):

• Platfrom Version: "orchid/platform": "^14.15"
• PHP Version: 8.1.2

Additional context
Code of etag generation:

'/css/style.css?etag='.md5(time()),

[ink-ru]

If we replace Etag to this code:

md5(floor(time()/60)*60)

problem solves

Of cause this is not a bug of Orchid, but maybe in future versions assets check feature may be added. E.g. "include_once" )
