[5.2] TinyMCe insert content

[brianteeman]

This changes the button text used when selecting a content template from "Save" to "Insert".

No additional changes are required for this to be translated as "Insert" is already translated.

(This PR was created at the request of "Daniel C K Tan" on facebook.

Testing Instructions

If you dont already have content templates set up and working for tinymce go to the plugin settings for tinymce and setup the correct folder

Then create a .txt file in that folder. (As this is just to test the UI the file can be empty)

Finaly in an article select the content template icon from the toolbar

And in the dialog that opens observe the text of the buttons.

Then apply this PR and retest. As it is a js change either apply the pr and then run npm i or use the prebuilt joomla package that can be found at the bottom of this page at the download link
