Solve visual problems in image manager

[MrMusic]

@eumel1602 has reported here that there is a visual problem in the image manager: https://github.com/JoomGalleryfriends/JG4-dev/pull/83#issuecomment-1486721378 In some selectboxes the texts are too long and cause a visual problem. This PR fixes the problem by using the shorter texts as in Joomla itself. See texts in Joomla article manager.

I have tried to change the language constants in the forms/filter_images.xml. Unfortunately, this does not work.

For Category Select Box: The previous text "Type or Select a Category" is loaded via the language constant JGLOBAL_TYPE_OR_SELECT_CATEGORY. This constant is used in line 71 of .../com_categories/layouts/form/field/categoryedit.php. To shorten the text I only see the possibility to redefine the constant JGLOBAL_TYPE_OR_SELECT_CATEGORY in the language file com_joomgallery.ini.

For User select box: For the selection of the owner I used the new constant COM_JOOMGALLERY_FIELDS_SELECT_OWNER in the UserdropdownField.php.

The text now fits into the box, it works! What I also noticed is that when I move the mouse over the selection of the category and access level, the mouse pointer is not displayed. see image. The function is OK with the "CLICK".

That works for me too.

And I also noticed something else. The opening windows look different for me.

EDIT: But this is not only the case in the JoomGallery - also with articles and article categories, for example.
