[Task]: Submissions Waffle Flag Follow-up

[chrstinalin]

Description

• The Theme Submission page (/en-US/developers/addon/submit/theme/upload-listed) has the Create a theme button still enabled when the flag is off

• The Theme Wizard page (that the aforementioned button leads to - /en-US/developers/addon/submit/wizard-listed) also has its submit button still enabled

• Some warning should be displayed somewhere on the upload & theme wizard pages and not just on the title of the disabled buttons, to make it more obvious. With the full note for consistency. From Add Waffle Flag for Submissions addons-server#22729 (review)

Hello,

I checked on DEV ENV' the submissions flag works as expected for themes and addon upload pages. Also a message is present on both upload pages when the submissions are disabled.

Thank you!
