PHP 8.2 deprecates string interpolation patterns that place the dollar sign outside the curly braces:
{{{
echo "Hello ${name}";
}}}
This commit fixes such patterns by replacing them with proper curly braced patterns:
{{{
echo "Hello {$name}";
}}}
This addresses `Deprecated: Using ${var} in strings is deprecated, use {$var} instead` notices when running tests on PHP 8.2.
