The MustacheResourceTemplateLoader previously defined the template
encoding as a String, defaulting to "UTF-8". This change replaces the
field with a Charset and initializes it with StandardCharsets.UTF_8.

Using Charset improves type safety and aligns with modern Spring Boot
standards, while avoiding implicit charset lookup issues.

Add setCharset(Charset) overload to MustacheResourceTemplateLoader
while keeping setCharset(String) for backward compatibility. The
String-based method is deprecated in favor of the Charset variant.

Also deprecate MustacheProperties.getCharsetName() as it's primarily
used with the deprecated setCharset(String) method.

This change maintains backward compatibility while providing a more
type-safe API that aligns with modern Java standards.

This replaces the use of charset name for our Mustache support.
