bump moto version

[eladkal]

We had to pin responses due to issue with moto lib #22046

moto fixed the problem getmoto/moto#4913 in 3.0.7 so we can just bump moto and drop the responses limit.

We will need to refresh constraints manually to merge this one, but yes :)

Temp doc build problem. Reopend to rebuild.

I'll rebase after either #22101 or #22100 merged and to resolve the sphinx issue.

[eladkal]

rebased

Generating constraints so that we can merge and push constraints at once (BTW. I am going to automate this case soon ).

[potiuk]

Actually moto has already been updated to latest version so we can merge it stratight away witthout re-generating constraints :);
