[4.1] com_media: hardcoded language strings

[pe7er]

The admin component com_media had some hard coded English texts.

Summary of Changes

This PR changes the hard coded English texts to language strings
and adds the translations to administrator/language/en-GB/com_media.ini

[brianteeman]

I may be wrong but my undeerstanding was that exception messages were not being translated

[pe7er]

I found the hard coded text when I was looking for the "Media Provider not found" that a J4 user reported to me when they tried to use Media as Custom Field Type.

If a decision was made to not translate exception messages, then that could explain why these strings weren't translated yet :-)

[brianteeman]

It appears to be inconsistent even within the same file and peersonally I don't understand why everything isnt a translatable string.

For example cheeck out https://github.com/joomla/joomla-cms/blob/4.1-dev/plugins/filesystem/local/src/Adapter/LocalAdapter.php

[laoneo]

A basic rule should be that the API throws a specific exception and the representation layer should catch it and display a meaningful error message. We tried to do this in the local adapter with the FileNotFoundException for example. But looks like some slipped through our fingers.

[brianteeman]

some? 12/15 is not some

[pe7er]

Thanks @brianteeman!

Marking as a successful test as it does what it says. Maintainers can decide if we do want to translate exceptions and then hopefully come up with a plan to update all existing hard coded exception strings.

Thanks. If this PR gets accepted, then I'll fix more of those hard coded Exception errors in components when I find them.
