application/javascript is deprecated. text/javascript should be used for js files

[MrRTi]

I had some issues with carrierwave content type checks and it resulted in founding out the usage of deprecated mime type by marcel

Ref about deprecation - https://www.rfc-editor.org/rfc/rfc9239.html#name-text-javascript

Deprecated alias names for this type: application/javascript ...

Current behaviour:

Marcel::Magic.by_path("tmp/data.js").try(:type) # => "application/javascript"

Expected behaviour:

Marcel::Magic.by_path("tmp/data.js").try(:type) # => "text/javascript"

When I checked the code I find that mime-types for javascript at

marcel/data/tika.xml

Line 335 in 170458c

<mime-type type="application/javascript">

have different order as in
https://raw.githubusercontent.com/apache/tika/main/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml
used at https://github.com/rails/marcel/blob/main/script/download_tika_data.rb

I suppose that could be a core of the problem.
