Remove double-quotes and improve message for " app has been accepted"

When an admin user accepts a pending App for publication release on App Store, a message with a pink background appears for a couple of seconds that states that the app has been accepted. It quickly disappears soon after.

First off, don't only show the message for a couple of seconds. Leave it on the screen and give the user a chance to read what it says and dismiss it when done. (Note: this should be getting fixed as part of https://jira.transvar.org/browse/IGBF-2184, but please check.)

Second, change the wording as follows:

• Remove double-quote characters surrounding the text.
• Change the message to use this much longer text:

Congratulations! You released App with Bundle-Name [insert value of Bundle_Name, in bold face font], Bundle-SymbolicName [insert value of Bundle-SymbolicName in bold face font], and version [Bundle-Version in bold-face font]. If this is the highest available version, please confirm that you can now install it using [this App Store page]. Also confirm that you can install the expected highest compatible versions within IGB using IGB App Manager. Note that all versions ever submitted to App Store – including this one – are listed on the App Store OBR index endpoint. Please check that, also!"

• Link this text: "this App Store page" to the App's page, e.g., https://dev-appstore-2.bioviz.org/Bundle_SymbolicName

• Link this text: "OBR index endpoint" to the releases repository XML for this App Store.
