Localize Text skips text that starts or ends on a new line #868

What happens

"Localize Text" skips text that starts or ends on a new line. The HTML patterns in get_text_replacement_patterns_for_html() have no s modifier, so . doesn't match a newline:

https://github.com/WordPress/create-block-theme/blob/5524f195e8/includes/create-theme/theme-locale.php#L217-L262

For example, this heading (from WooCommerce's Related Products markup) is exported unchanged:

<h2 class="wp-block-heading has-x-large-font-size">
				Related products			</h2>

The same happens to a paragraph like <p>\n\tNo products were found matching your selection.</p>. It affects every block type in that list, not just headings.

A side effect: when nothing in a template gets localized, the template isn't moved into a pattern either, because paternize_template() only runs when PHP was added.

Expected

The text is wrapped in esc_html_e(), with the surrounding whitespace trimmed.

Suggested fix

Add the s modifier to these patterns and trim the captured text before escaping it.
