Use application/javascript instead of obsolete text/javascript for Content-Type

[westonruter]

Apparently text/javascript is obsolete and should now be application/javascript. So this should be changed:

pwa-wp/wp-includes/class-wp-service-workers.php

Line 116 in 943de6d

@header( 'Content-Type: text/javascript; charset=utf-8' ); // phpcs:ignore Generic.PHP.NoSilencedErrors.Discouraged, WordPress.PHP.NoSilencedErrors.Discouraged

Humm, apparently I'm mistaken. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types#textjavascript

Apparently we shouldn't be including the charset=utf-8, though? But how else would the browser know the character set?

[westonruter]

Although perhaps this only applies to the type attribute on script tags, and not to the HTTP Content-Type response header.

Nevertheless, nobody has reported this as causing a problem, so there doesn't seem to be a need to change anything.
