Link to issue number:

Fixes #15042

Summary of the issue:

The title of add-on store window is formatted such as "Add-on Store - All Installed add-ons"
After the dash, the string is a concatenation of the channel and the type of add-ons in the list.

• In English,it makes something almost grammatically correct to build a single expression (if we ignore case). But in other languages, this concatenation without any separator may produce stranger results that sound bad.
• Also, it has been noted that the type of add-on listed ("Available add-ons" in this example) is much more important than the channel; thus it should come first.

Description of user facing changes

• Reworked the window title to create a title such as "Add-on Store - Installed add-ons (All)"
• While at it, also removed the channel in the list name as pointed in Modify the add-on store title bar text #15042 (comment), that is, the list's name is now "Available add-ons" instead of "All Available add-ons" so that the list name is less verbose.

Description of development approach

Implemented changes described below.

Note: I have used parenthesis for the channel, but I may have used a second dash as a separator instead, i.e. "Add-on store - Available add-ons - All". Let me know if you prefer this second version.

Testing strategy:

Manually checked the window title and the list name.
