Small typo in the submit-field

[rubyFeedback]

Hello xmisao,

Right now the text is:

"If you believe it, please type believe into the following textbox and click a submit button."

I think the last part:

click a submit button

should be changed to:

click the submit button

The reason as to why is that "a submit button" is unspecific, but we have one submit button below, and only one there. So I think "the" is better than "a" in this context.

Thanks for reading this!

(Or perhaps even "click on the submit button below", to make this even clearer to the visitor.)
