Migration message at bottom of screen is incorrectly capitalized

Discovered while testing MCL-16237. Relates to WEB-3323.

The bug

The migration message shown at the bottom of the screen to users who have been presented the migration dialog but have chosen 'Migrate later' is not capitalized properly. The message reads:

Microsoft Account capitalizes 'Account'. This is inconsistent with other uses of this term, as this is always lowercase in other places.

How to reproduce

1. Ensure the Minecraft Launcher is not open, and that your device is not connected to the Internet
2. Navigate to your minecraft folder -> open launcher_accounts.json
3. Locate the line "eligibleForMigration" : false, and change the false, to true,
4. Save and exit the file
5. Open the Minecraft Launcher, and click 'Migrate later' in the dialog presented
    Notice how the message at the bottom of the application contains the incorrect capitalization
