[Themes] | Smarty: SVG file includes throw fatal error after re-mapped for Blade file paths

Description

In OJS 3.5, it is possible to use the Smarty template syntax to load a .svg file (or a file with any other file extenstion). Example:

{include file="frontend/icons/dropdown.svg"}

In the current main branch, this throws a fatal error:

PHP Fatal error: Uncaught InvalidArgumentException: View [frontend.icons.search.svg] not found.

The problem seems to be related to PKPTemplateManager::smartyPathToViewName(). The file extentions .tpl and .blade are removed before slashes are converted to dots, but the dots remain for other file extensions. I have not tested this, but I believe an error will occur whenever a . appears anywhere in the middle of a filename, such as /frontend/example/article.header.tpl.

I can work around this by renaming my .svg files to .tpl if necessary. However, this may cause problems with other custom themes out there.

Steps to Reproduce

1. Login as an admin.
2. Enable the IndividualizeTheme or add {include file="frontend/icons/dropdown.svg"} to any default theme template (like header.tpl).
3. Activate the theme and load a page on the frontend.
4. See the error.

Expected Result

The .svg file should load and there should be no fatal error.

Actual Result

Fatal error.
