"Avoid using self-closing tag" rule is false positive with inline svg

As SVG content must be in XML format it must be excluded from HTML validation.

### Preconditions
1. Installed Magento Coding Standard V19 or above

### Steps to reproduce
1. Add inline svg to test.html file
2. Run `vendor/bin/phpcs --severity=10 --standard=Magento2 --ignore-annotations test.html`

### Expected result
1. No errors appear

### Actual result
1. Errors are appear
Avoid using self-closing tag with non-void html element - ``

Start by reproducing the issue with test.html and the documented vendor/bin/phpcs command under the Magento2 standard. Trace the HTML validation rule that reports the self-closing SVG rect element; done means inline SVG is excluded from this validation while the existing non-void HTML checks continue to report errors.
