Bug Description

[Impact]

This is a follow-up of bug #1891733. After the new default font for Arabic had made it to focal, we got some additional feedback at <https://discourse.ubuntu.com/t/14573>. After further discussion, trial and error, and multiple changes in groovy it has landed in a consensus to make these adjustments:

* Rename the .conf file from 69- to 56-

* Drop binding="strong"

* Drop the specification for monospace, and with that fall back
  to DejaVu for Arabic monospace

The significance of the changes, which motivates the proposed SRU, is made up of:

1. Use DejaVu Sans Mono as default Arabic font for monospace
   instead of the previous non-mono font

2. No longer conflicts with Kubuntu's custom font configuration

[Test case]

* Install the language-selector-{gnome,common} packages
  from focal-proposed.

* Open the Language Support tool and install Arabic.

* Open a terminal window, run the below commands and confirm
  that you get the same output:

  $ LC_CTYPE=ar_EG.UTF-8 fc-match
  NotoSansArabicUI-Regular.ttf: "Noto Sans Arabic UI" "Regular"
  $ LC_CTYPE=ar_EG.UTF-8 fc-match monospace
  DejaVuSansMono.ttf: "DejaVu Sans Mono" "Book"

[Regression risk]

For some users this will change the default monospace font for rendering Arabic. That's the point. :)

The change will only affect users with an Arabic locale. The risk that other users would be affected by the change is low.

Looks like DejaVu must be specified explicitly for monospace.

Better handling of the issue mentioned in comment #5:

* Rename the .conf file so the name starts with 56- instead of
  69- (makes it lower than 57-dejavu-sans.conf)

* Drop 'binding="strong"'
