Build/Test Tools: Remove the replace:emoji-banner-text Grunt task.

The task was previously used to ensure that `/*! This file is auto-generated */` comment is not included on front end as part of the inline emoji detection script.

As the `wp-emoji-loader.js` script is now included via `file_get_contents()` and `wp_print_inline_script_tag()` instead of `grunt-include` to simplify the logic, the task does not find anything to replace and is no longer necessary.

Additionally, include a line break before the `wp-emoji-loader.js` script content for better line wrapping.

Follow-up to [48096], [50651], [52132].

See #44632, #44306, #53363.
