refactor: update ECMA script types

[fritzchr]

Some ECMA script mime types were obsoleted in favor of 'text/javascript'. For a full reference check RFC 9239 (https://www.ietf.org/rfc/rfc9239.pdf).

The media type registrations herein are divided into two major categories: (1) the sole media type "text/javascript", which is now in common usage and (2) all of the media types that are obsolete (i.e., "application/ecmascript", "application/javascript", "application/x-ecmascript", "application/ x-javascript", "text/ecmascript", "text/javascript1.0", "text/javascript1.1", "text/javascript1.2", "text/ javascript1.3", "text/javascript1.4", "text/javascript1.5", "text/jscript", "text/livescript", and "text/xecmascript"
