Add developer survey in doc

[yuxizama]

Added the developer survey banner in the most viewed docs and README page to promote the survey and gather feedback.

Hey @RomanBredehoft
I made a small adjustment yesterday and it seems like some tests have failed.
For this message below I don't really understand what happened. 😅

"@yuxizama yuxizama dismissed RomanBredehoft’s stale review via c7a6f22 18 hours ago"

Could you please help to check?
Besides, I would like to merge the same changes into the 1.6 branch so that i can be reflected on the Documentation website, but I'm not sure what's the best way to do it. Should I create another PR with these changes for 1.6 branch?
Thank you!

[RomanBredehoft]

Yes @yuxizama , sorry for the delay, I just committed and it should fix the issue !

And no worries for Gitub's message, in this repo we've enabled a setting which makes new commits dismiss all approval from PRs (we prefer to re-review if new changes have been made) 😉

as for 1.6 yes the idea is to open a new PR targeting the release/1.6.x branch and include the same changes !

Great @RomanBredehoft thank you so much! I'll do it for the 1.6 branch
