Use the recommended way to render an image: through the HTMLHelper

Testing Instructions

Check that selecting a custom logo image works and that the source doesn't have the hash part of the URL. Also check that svg renders as expected

Actual result BEFORE applying this Pull Request

The URL contains the hash (it is dirty) and SVG images get 0 width and height thus are not visible

The URL does not contain the hash (it is clean) and SVG images are visible

Double //. Also image does not display on the frontend.

@Quy should be ok now, thanks

The double slashes is fixed, however, the image won't display even though the markup is there. Adding a width attribute displays the image.

<img loading="eager" decoding="async" src="http://localhost/joomla-cms-4.2-dev/images/logo.svg" alt="J42">

Ok, this could be solved either with CSS (patch) or the media manager needs to pass the correct size when an svg is selected (proper solution). I would make a PR for the second option.
This PR is still valid as it cleans the URL #...

@Quy @viocassel thanks for testing this one. #39586 is the last missing part (the one I wrote about here: #39574 (comment)) and would be awesome if you could test that one as well. Mille grazie
