[Impact]
The Livepatch / Help improve images aren't transparent enough to match the design.

[Test Case]
1. Run initial setup:
$ /usr/lib/gnome-initial-setup/gnome-initial-setup --existing-user
2. Go to the "Livepatch" page

Expected result:
Images are shown with 75% transparency

Observed result:
Images are shown with much less transparency (too dark).

[Regression Potential]
Low, just adjusted alpha value.
