The indentation is off below.

I recently noticed this pattern of shipping only Poetry in the
repository while at the same time not shipping tests in PyPI. I don't
know why this is happening or what we can do about it in guix, the best
for now is to source from PyPI and skip tests like in this package.

The two lines above are redundant. The second line is the manual way of
doing what the first one does. But if we don't have a way to run the
tests, I'd not override the check phase.

Test-related native inputs are also useless if tests can't run.

Same line for the synopsis.

I'd suggest "TinyDB is a small document oriented database written in
pure Python with no external dependencies. [...]".
