[Homepage] Survey on the top: perhaps add some hint or indicator when this was added/created and for as long it is useful / in use

[rubyFeedback]

Hey folks,

At the homepage of GraalVM here:

https://www.graalvm.org/

You see a survey on the top. I also see a 'X' icon to click it away so no problem.

I believe I have already answered the survey some months ago, but I am not 100%
sure; and it may be another survey, after all.

My small suggestion here is to add an indicator WHEN this survey was added; and/or
for how long it will be up.

There are a few ways how to implement this. A simple one may be a tiny pop-up
with a "fade-in" effect on mouse-over effect, e. g. "This survey has been created
on the DATE_HERE and will run until FINAL_DATE_THERE." or something like
that. Of course there are other ways how to approach this, so the above is just
one simple example. If it were my homepage I'd add a e. g. 2 seconds delay
fade-in via mouse-on-hover to indicate the duration validity of the survey.

As it is right now, I assume I already answered the survey some months ago,
so I will click on the 'X' next; evidently if this is a newer survey then I may
never again visit it, as I do not know whether I already went through it or
not.
