fix(app): fix center aligned app release notes

[mjhuff]

Closes RQA-2360

Overview

This one is funny. Several months ago, for some reason I don't understand, I tried to CSS text-align: center the update modal text. However, I made a typo, textalign, which kept the text aligned properly.

Present day (well, a few days ago). @koji was nice enough to notice the typo and fixed it while updating colors. This caused the dormant text-align bug to appear.

The fix - we don't need text-align here :)

Before

After

Test Plan

• Here is a special build of the app that is 7.2.0-alpha.2 + this commit.
• Launch the app, enable the alpha update channel, and try to update the app. Note that the release notes are properly left-aligned now.

Changelog

• App release notes are no longer center-aligned.
